TF17AJ9
The beauty of modest and rare form and color. An aerial group of strongly elongated Chalcocite crystals with very well defined faces and edges, arborescent recrystallizations on terminations and coated by fine botryoidal growths of iridescent Chalcopyrite that have dominant blue and green metallic shades. We know from existing references that Djurleite partially substitutes for most of the crystals.

TR76AJ9
Very aerial and elegant group of Gold crystals with the well-defined crystalline forms of the octahedron and the dodecahedron. They are elongated, some of them with “window” and skeletal growths and some laminar forms.

MR26AJ9
Different from Helvine crystals from other Chinese provenances, these are isolated, sharp and formed by the positive and negative rhombohedron, with the color between dark honey brown and yellow distributed in zones. They are on a matrix coated with orange trapezohedral Spessartine crystals and leafy aggregates of Chlorite. The Helvine has been analyzed and we will send a copy of the analysis to the buyer.

TE48AJ9
The intense ruby-red color and the brightness of the equant Cinnabar crystal contrasts with the snowy white of the rhombohedral Dolomite crystals, with fine curvatures on faces and edges. Simply fascinating.

EA92AJ9
Different from the more well-known Bolivian Valentinite, this one is in spheroidal aggregates of radial acicular crystals that are on a limonite matrix, have very well defined faces and edges, are very bright and have a uniform yellow color.

TV50AJ9
Very well known in mineral collecting the beauty of these complex Sphalerite crystals never ceases to amaze us. They are translucent, very bright and with a very deep color, on a matrix coated bay small Quartz crystals and cubo-octahedral Galena crystals with very well defined faces and edges.

AG96AJ9
This beautiful sample is not very large but it possesses a lot of esthetic qualities such as an intense luster, a color of an especially deep and vivid green shade, and the morphological variety of the crystals that varies from the acicular shape to the prismatic habit with pinacoidal terminations or parallel growths of doubly terminated crystals with polycrystalline or hollow terminations. A small jewel from the Silvane collection whose label we will send to the buyer.

TB49AH3
Accustomed to a very different esthetics on Pyromorphite samples from the Daoping mine, the finds between 2012 and 2013 surprised us with these very aerial and stylized shapes, whose crystals have very well defined faces and edges and showing a color and luster of great quality.

TR91AJ9
One of the attractive aspects of the sample is the contrast between the dark crystalline matrix and the pale shades of the elongated Pyromorphite crystals, a lot of them doubly terminated, with hollow terminations and partially coated and replaced by Plumbogummite of a pale blue color.

MA86AH3
Plumbogummite growths that are between botryoidal and stalactitic. They have an intense greenish-blue color and velvety surfaces and they have empty cores with the shape of lost Pyromorphite crystals as well as some yellow traces of these former Pyromorphite crystals. The sample has been analyzed and we’ll send a copy of the analysis to the buyer.

MP88AJ9
A very well balanced sample which spotlights their transparency and the luster and diaphaneity of the octahedral Fluorite crystals beveled by the dodecahedron and the cube, and the right matrix with Quartz, Calcite and Dolomite.

MP89AJ9
Another demonstration of the morphological and chromatic diversity to which the Chinese Fluorites accustomed us. In this case a group of cubic crystals that are transparent, bright, with a deep green color and strategically placed on a group of Quartz crystals with recrystallizations and partially coated by equant Calcite crystals.

TL68AJ9
The sample is especially attractive due the contrast between the thin and sharp forms of the rosette aggregates of the laminar Hematite crystals, very bright, and the rounded outlines of the aggregates of white Quartz crystals with the “artichoke-like” shape.

EV97AJ9
Perhaps simply Quartz but it has a surprising variety of forms and morphological changes, with parallel growths on the scepter terminations, dipyramidal, with a short prism (in some cases those faces are nonexistent or poorly visible and such crystals have sometimes been erroneously described as β-Quartz). The Quartz group is very rich in inclusions and partially coated by small, white Calcite-Dolomite crystals.

MR90AH3
The year 2010 saw the ringing of the bell of the first great samples arriving from Huanggang, a mining area of which little had been spoken of until that moment. Among the novelties there were some Ilvaite samples with crystals of great size with very well defined faces and frequently with Quartz crystals. In a very short time these samples became classic, not only for China but also for the rest of the world.

ET96AH3
Even the most well known occurrences can adopt different forms, new or attractive, as this irregular surface completely recrystallized on both of its ends by transparent cubic Fluorite crystals with an intense violet color. Similar to a geode, but fully upholstered by Fluorite crystals “in” and “out” at the same time…

TB50AJ9
Another sample with great impact, a group of clear Quartz crystals with reddish zones due to Hematite inclusions and partially coated by rosette aggregates (iron rose variety) of laminar Hematite crystals and a group of dipyramidal Helvine crystals. The Helvine, from the East Ujimqin Banner area and not from the classic Huanggang mine, has been analyzed and we will send a copy of the analysis to the buyer.

EA89AJ9
If the variation is pleasant, what better than this association of four species, two of them (Roweite and Olshanskyite) very rare? The Roweite is in aggregates of laminar crystals of great size and quality for what has been known for the species, and it is on matrix, with very sharp, clear and colorless Olshanskyite crystals, small Andradite crystals and octahedral Magnetite crystals. The Roweite crystals are neatly differentiated and have well defined faces and edges with a light creamy color. The quality of these specimens is undoubtedly superior to what was previously known, both for the individuality of the crystals and for their sharpness, but also for their association with first level Olshanskyite crystals, which makes them deserving to be in the best private collections and museums. We have analyzed samples to confirm the identity of the different species and we’ll send a copy of the analyses to the buyer.

ED18AH3
Mineral rarities can also have particular beauty, as is the case of these rare borates coexisting on the same sample, where the lenticular Roweite crystals, with an orange color and of great size and quality for what has been known of this species, are with radial aggregates of very sharp, colorless, clear and very bright Olshanskyite crystals plus also ornate by Calcite and nice Magnetite! The quality of the specimens is undoubtedly superior to what was previously known, both for the individuality of the Roweite crystals and for their sharpness, but also for their size and their association with first class Olshanskyite which makes them deserving to be in the best private collections and museums. We have analyzed specimens to confirm the identity of the species and we will send a copy of the different analyses to buyers.

MT90AJ6
The Xuebaoding Beryl is characterized by its tabular morphology, well known but not common for the species. The crystals are transparent to translucent and have a very attractive and uniform light sky blue color and are on a matrix of Muscovite crystals.

NH66AH3
Geometry and a very intense luster characterize this twin of two crystals, a twin that is splendidly well defined and that has the added “touch” of very sharp laminar and perfectly defined Muscovite crystals.

EJ87AH3
Esthetics and mineralogy are joined on this elongated Fluorite sample, with Fluorite crystal cubes that are translucent, with a lilac color on their interior and strongly saturated violet color on their edges, and they are partially coated by Baryte on the back. They have grown around a fine elongated Stibnite crystal that is partially visible due to the transparency of the Fluorite.

TF90AH3
Among the many and nice incentives that Chinese mining has provided us in recent years there are some scarce samples of botryoidal Hemimorphite with an especially intense and vivid blue color, with a surprising resemblance to the classic and very well known samples from the Sa Duchessa mine, in Sardinia.

TX28AG1
In 2009, very curious Calcites with milky tops and bottoms, transparent lateral faces and "jungles" of inclusions of what seems to be a kind of mud, appeared in China. As fast as they appeared they disappeared and as far as I know it was never known exactly where they came from beyond "Lishui." This is a good example of this unusual find.

MR88AG1
Yes, it is Calcite, a very common species, but check out the crystallographic habit of this group of crystals and their light pink color. Different…

TC13AG1
Monumental, a top specimen. Few Acanthites are as impressive as those from this mine and this one in particular stands out for its extraordinary quality.

EE36AJ9
On a species generally appearing on the gamma of white or gray, draws our attention the pleasant orange-red color selectively distributed in the very well defined trapezohedral crystals, one of them clearly dominant.

EC16AJ9
For a species generally appearing with the color of white or gray, our attention is drawn to the pleasant orange-red color selectively distributed in the very well defined trapezohedral crystals of this specimen.

TH96AJ9
We must especially note the esthetic quality of this kind of floater Cerussite aggregates forming multiple twins of very sharp crystals that are between laminar and tabular, transparent, very bright and more neat and perfect than most of the samples from this locality.

TJ17AJ9
We must especially note the esthetic quality of this kind of floater Cerussite aggregates forming multiple twins of very sharp crystals that are between laminar and tabular, transparent, very bright and more neat and perfect than most of the samples from this locality.

TP86AJ9
We must especially note the esthetic quality of this kind of floater Cerussite aggregates forming multiple twins of very sharp crystals that are between laminar and tabular, transparent, very bright and more neat and perfect than most of the samples from this locality.

EB50AH3
Different and aesthetic. Aggregates of cyclic twins of tabular Cerussite crystals that are finely bordered by very thin and acute Mimetite microcrystals with a very vivid orange-red color. These Mimetites have been analyzed and have proven to be a rare chromium-rich variety. We'll send a copy of the analysis to the buyer.

MK87AJ9
Very aerial and esthetic arborescent and flattened growth of Willemite crystals after Descloizite, partially coated by small barrel-shaped Mimetite crystals, a lot of them doubly terminated, with an intense reddish yellow color.

MH46AH3
Seen and unseen, these samples that appeared at the Munich Show in 2015 are currently a rarity. They form arborescent growths of Willemite crystals pseudomorphous after Descloizite and have partial coatings of small barrel-shaped Mimetite crystals with an intense orange color.
This specimen was published on the Mineralogical Record´s web page, in the ‘What's New’ section, report 49, May 7, 2018 edition.

TM96AH3
The most innovative of this Iranian Mimetite sample is, undoubtedly, its sharpness and that its tabular crystals have a color, a transparency and a luster that are unusual for the species. In this concrete case we must note their esthetic growth on a matrix of white Calcite crystals.

TZ43AJ6
The sample is very rich with Gold with arborescent crystalline and skeletal forms on a Quartz matrix. We will send the sample it in its original Perkin’s box from the R.J. Noble collection, also containing the collection label on which appears the note: Kalgoorlie, 2004, 13.8 grams net.

TC16AJ6
A very fine and aerial Gold growth with large leafy crystals. The sample is of an uncommon quality. We will send it in its original Perkin’s box from the R.J. Noble collection, also containing the collection label on which it appears that it was purchased from the Normandy Mining Limited Bronzewing Operations in 2003.

EH37AI6
A Broken Hill Anglesite with the special appeal of the ancient (the “oldies”) samples. The Anglesite has completely pseudomorphed a group of flattened Cerussite crystals with a coralloid aspect and that have a white color with pinkish shades.
The sample is from the René Hubin collection whose label we’ll send to the buyer with other two old labels that were with it.

ME68AI6
A Pakistan Beryl (aquamarine variety) crystal, very similar to old Brazilian samples, with the pinacoidal termination beveled by several pyramids and with inner phantom growths and dissolution channels all along the interior of the crystal.
The sample is from the Carles Manresa collection whose label we’ll send to the buyer.

EQ96AG1
The good definition and morphology of this Lazurite on Calcite takes us back to the time in which from this locality the "lapislazuli" was extracted and distributed throughout the world via the Silk Road.

TV88AJ6
Of the polychrome Elbaites from the Himalaya mine one of the characteristics that the 'photographic eye' most appreciates is the geometric color zoning, in this case from the bottom to the top there are three superimposed delicate pastel colors: yellow, pink and green. A 'delicatessen'. We will send the sample in its original Perkin’s box from the R.J. Noble collection, also with the collection label on which it appears that it was obtained in an exchange with Terry Enright, June 2011.

NT89AJ6
Typically from the classic Red Cloud mine the tabular crystals are very sharp and are implanted on a limonite matrix, showing all of their splendor and beauty with the perfection of the crystal forms and the intensity of their bright red color. The sample is from the Ignacio Hernández collection whose label we will send to the buyer.

TE37AI9
A floater group of pyritohedral crystals without minor forms, with very well-defined faces and edges, very bright and partially coated by growths of calcite microcrystals. The specimen is from a locality where good Pyrite specimens are not so common.

TA68AG2
"Electric blue" is the proper name that has been given to the color of the best Azurites from Milpillas. Certainly these Azurites seem to have their own light as if they emit light instead of capturing it. This small filigree represents very well that "electric" color as well as the best quality of the Milpillas Azurites.

TP16AI9
Pseudocrystals of Malachite after Azurite in parallel growth on a matrix of fibrous Malachite: bright, with very rich color.

TH16AI9
This is a single, sharp, doubly terminated floater of Malachite pseudomorphous after Azurite, apparently simple, but the polycrystalline growths are full of interesting details.

TG99AI9
This is a group of pseudocrystals of Malachite after Azurite, one of them clearly dominant, with very well-defined faces and edges and a very deep color, partially coated by fibrous Malachite.

TA30AG1
Milpillas is in recent times a kind of lighthouse for the fans of minerals from all over the world. Within the extensive catalog of spectacular minerals their Cuprites are not the most recognized, but their quality is very high.

TL62AI9
Brochantite crystals from Milpillas are famous for their sharpness and generally excellent quality. Here we have a group of idiomorphic Brochantite crystals with well-defined faces and edges and chisel-like terminations. The specimen’s composition, with large crystals on matrix coated by smaller crystals, makes for fine aesthetics. In my opinion this locality produces the world’s finest Brochantite specimens.

TR88AI9
Brochantite specimens from Milpillas have won a well-deserved fame for their excellent quality. In this case, the idiomorphic crystals are elongated,with sharp faces and edges and a very deep green color; the matrix is partially coated by a later generation of brochantite, showing pale green fibrous crystals with satiny luster. In my opinion this locality offers the world’s best Brochantite as judged by crystal size and sharpness, deep color and high luster.

TA70AG2
Most of the mineral species that the Milpillas mine has produced are the best of the best. The Brochantites are part of this rating and this piece is a good example of it for its excellent color, its richness of crystals, and the fact that the crystals are on a rock matrix.

EK57AI9
Milpillas Volborthite specimens are without doubt the world’s best: with their large crystal size and high luster they set a new standard for this rare species. This small specimen shows a rosette-shaped growth of flattened Volborthite crystals on matrix; the rosette is very sharp and deeply colored.

TD89AG1
Not all Volborthites are expensive! This group of crystals with a color change on top is not bad at all. The change of color, which may look like a break, makes its price reasonable.

TR13AG1
The Volborthites of Milpillas are among the most spectacular discoveries that have happened in the mineral world in recent years. In general they are of an enormous quality and in aspects this great rosette of crystals with Malachite and on matrix stands out among all others. If someone wants a definitive piece, here it is.
The specimen has been reviewed, photographed and published in the magazine ‘Mineral Up’ on page 69 of the 2017/01 edition

TF86AG1
Divergent groups of crystals of Adamite on a limonite matrix, with the centers of the crystals violet and a yellow body. Good display of the crystals and in general a different aspect from the usual one. It is not an Adamite like others.

TE87AG1
Boleite with Atacamite-Paratacamite on matrix. Coming from recent finds in the famous Amelia Mine due to work on the dumps there.

TQ51AG1
Creedites are well known from this mine, but their Fluorites are not as well known and yet they are excellent; octahedral and violet and more rarely in very large crystals such as this one. On a base of Quartz and a first generation of green Fluorite, the collector José Luis Vallecillo was right in his choice of this powerful Fluorite.

TA97AG8
The Quartz from this Quarry which is already defunct (currently is completely flooded) is a world's reference due its quality and brightness. From the glorious past comes this beautiful group of Quartz crystals, several of them doubly terminated and partially coated with small scalenohedral crystals of Calcite.

DP16AG6
The Daunis collection is a faithful mirror of the minerals that were found in Spain in the 60’s and 70’s. The Asturreta Quarry, specifically the area called "El Pozo," produced in those years the best known Dolomites and Daunis had the ability to get some of them of extraordinary quality. This piece is a good example.

NP90AG2
The upper levels of the great classic mine of Panasqueira are now producing very good specimens. We have gone from a period of scarcity to the current wealth, but in my opinion we are in a transitory period that may end when the mine goes to different areas. So far several pieces as attractive as this zoned crystal of Fluorapatite have been recovered, isolated and well placed on its matrix of Quartz and Muscovite.

EP69AJ6
Radial and fan-like aggregates of acicular Kermesite crystals. They are extraordinarily bright and have an intense deep red color, on matrix with small white Calcite crystals.

ME14AJ6
Fine and aerial botryoidal growth of rhombohedral crystals that are between yellow and orange, contrasting nicely with white Calcite coatings.

EE57AJ6
A classic aggregate of Malachite crystals after Cuprite, formed by the cube and the dodecahedron. Its clear and uniform green color contrasts with the deep blue of the nodule of equant Azurite crystals. A French classic.

EF88AJ6
A complete floater nodule of very sharp equant Azurite crystals that are bright, have a very deep color, and are with small octahedral Malachite crystal pseudomorphs after Cuprite.

EJ66AJ6
Druse of well-formed Pyromorphite crystals, some of them doubly terminated, unusual for Le Vidale where they commonly form spheroidal aggregates. A good greasy luster and the uniform green color enhances the sample.

EV86AJ6
Small groups of Pyromorphite crystals with strongly curved faces and edges, with a greenish yellow color, bright, very aerial and on a Quartz matrix. The esthetic appearance of the sample is notable, very much better than usual for the locality.

MG30AI6
A sample that reclaims a special attention, both for its spectacular appearance and for its complexity, because the Galena has the pseudomorph shape of parallel growths of old tabular Pyrrhotite crystals coated by Pyrite further recrystallized in small cubic and cubo-octahedral crystals, and with some twinned Sphalerite crystals. Being that the Pyrrhotite is after Galena and not Pyrite (which is the the most typical) the chemical stability of the sample seems assured.

EP40AI6
The well known aesthetics of the Kosovar samples enhance some minerals that are currently considered as “modest,” as is the case with this Galena that forms cubo-octahedral crystals that are twinned according to the spinel-law, some of them flattened, all them extraordinarily bright and on matrix with Quartz crystals.

EJ89AG8
The great mining region of Trepča is one of the largest polymetal deposits in the world and it has given for many years exceptional pieces of Sphalerite as well as varied combinations of sulfides and carbonates. This old piece, found before the mine went back to work in 2005, presents an architectural group of large rhombohedral Dolomite crystals partially coated by Calcite crystals and with a cluster of Pyrite crystals on one side of the piece. Small crystals of Arsenopyrite dot the large Dolomite crystals and also some small Quartz crystals complete the combo.

CA91AI6
Relatively common in the eighties the Celestine samples from Machov had a great success in the collectible mineralogical world due both for their strict mineralogical interest and the esthetic appearance of the crystals, elongated and transparent, often with smoky shades and extraordinarily bright. They are currently considered as classics of mineralogy and there are few samples for collectors. To all this we must add that the Celestine has the unusual property of being phosphorescent (during 1-2 seconds)

HD14AI9
This specimen represents a classic Italian locality for Ilvaite. It is one of the better known localities for the species, but only a very small number of specimens from it have ever been recovered and saved. The Ilvaite crystals, some terminated sharply on one end and less sharply on the other end, are highly lustrous. Small quartz crystals are associated.

TP48AH3
Thinking of Grossular localities it is very probable that the first in our mind will be Val d’Ala. The crystals, very well defined and combining the forms of the dodecahedron and the trapezohedron, with splendid color and luster and the presence on the matrix of Diopside and Clinochlore crystals do this sample great credit as an Italian classic.

ET92AG6
We love the classics, and when they are good then it is the best! This classic from England easily was found 100 years ago and reflects very well a period in the history of minerals in which the United Kingdom was the reference for many mineral species, including Pyromorphite.
The Moutet collection from Marseille is the origin of this piece and the label of the prestigious shop Deyrolle de Paris that accompanies it is as historic as the Pyromorphite itself.

TN89AG1
Rudabánya is a classic European town famous for its Cuprites replaced by Malachite and although there are also Azurites they are normally of modest quality. This piece, however, is of good quality and size and improves on what is usually seen coming from that mine.

TX97AH3
You can opine, perhaps, that Calcite is a “modest” species, but it can also reach unexpected heights of elegance as in the case of this complete crystal that is clear, colorless, very rich in faces and has additional elongated Calcite and Aragonite crystals with curious parallel growths. Due to its special transparency, the Calcite crystal has a high birrefringence that allows one to see “double” images through it.

EB66AG6
Between 1997 and 1998 there appeared in the 2nd Sovietskii Mine from Dalnegorsk specimens of red Quartz with a very different habit from the usual, elongated, crisscrossed, and forming very "sculptural" groups. Although at that time it was thought that they would continue to come out, as soon as they appeared they disappeared and they have not been seen again. From that extraordinary time we have rescued this elegant specimen in which the red Quartz is partially covered with white Quartz.

FF71AI9
An aesthetic group of octahedral Fluorite crystals with polycrystalline growths on the edges. The translucent Fluorite crystals have a very deep violet color, and they share their matrix with cubic Pyrite crystals and small Quartz crystals. The specimen is from a mine which went extinct many years ago.

TB37AG6
There are few good Djurleites left from the ones recovered at the Aït Ahmane Mine between 2014 and 2015. We were lucky to be able to gain access to the finest pieces during Tucson 2017 and we still have some of great quality. This one in particular is the best we have left. These large crystals with good definition, both on the front and on the back, and with some minor matrix makes an excellent specimen.

EX89AJ6
The sample, a single crystal, is a complete floater with an uncommon morphological appearance. It has a base with two opposite polycrystalline terminal areas and an enlargement of the crystal that finishes with a very acute pyramid. To the curiosity of the crystal shape we must add the attractive color, between green and yellow.

NF29AI2
Luminosity and balance are surely the terms that best define this specimen which displays a pinacoidal termination of the Elbaite crystal that is extraordinarily sharp and bright and with prismatic faces that are very well defined with a marked color zoning, green on the terminal half and a vibrant pink on the bottom half. The matrix, with leafy aggregates of Mica some of them very aerial, add the final aesthetic touch.

TM49AI2
Some minerals are fortunate, either for the time they were discovered, or by the circumstances of their discovery or even by the place where they were found and beyond their greater or lesser beauty, of having become true myths of mineralogy. This is what happens with the Grandidierite of which, in addition, recent discoveries of an exceptional quality have been made to date, as is the case with this splendid individual flattened crystal with faces and edges unusually sharp and with the top termination very well defined while the lower termination is polycrystalline and somewhat rough. The crystal is bright, between transparent and translucent and it has a very deep and uniform bluish-green color.

MQ53AG6
In 2017 in the N'Chwaning I Mine some manual work for the extraction of collector’s specimens was reinitiated. This fine Rhodochrosite is a good example of the result of this work. Good color and great luster are the hallmarks of this piece.

TN56AG8
Sceptered Quartz variety smoky from an isolated find in which the upper part of the crystals is of an excellent smoky color and the lower part on which the scepter grows is milky Quartz with faces coated by parallel growths of small crystals, also Quartz.

TA27AI9
The Desmond Sacco collection has frequently bestowed small treasures on us, such as this group of Wulfenite crystals on matrix. The yellowish crystals are very sharp, very lustrous and translucent. We will send the former collection label to the buyer.

TM54AJ6
The crystal, completely transparent, is very bright and very rich with pyramidal terminal faces. It is notable for its luster, its clarity and its intense yellow color. A small jewel we will send in the original Perkin’s box from the R.J. Noble collection, also containing the collection label on which it appears that it previously was in the Bob Sullivan collection.

NF90AJ6
Very aerial polycrystalline growth of very bright and transparent crystals with sharp 'window' growths. An old Brazilian sample, a classic.

TF90AI2
The gemstone deposits of the Brazilian pegmatites will never cease to amaze us. This is the case with this specimen, rich in elongated crystals of Elbaite with a considerable variety of terminal forms (many recrystallized), a bright green color and in a Quartz matrix, and with leafy aggregates of a Mica which, according their violet shades, could be Lepidolite.

MV37AJ6
Surely this ample offers the most classic image of what a native Copper sample should be, with delicate and very well balanced arborescent growths of crystals with rounded faces and edges and with the precise matrix to give it the necessary esthetic character.

MF98AJ6
Colombian Gold samples with a certain esthetic quality are really rare so we must note the finesse and the richness of the leafy Gold growths of the sample we present here, a sample that comes from the Raúl Sanabria collection whose label we will send to the buyer.
