Main crystal size: 2.7 × 2.4 cm = 1.06” × 0.94”

FC76: A curious specimen. It is a Dolomite totally covered (but not pseudomorphosised) by a thin chocolate cover of iron oxides. First impressions when you look at the specimen are: nice Siderite! When you look more carefully you will discover that the primary crystals are really white curved Dolomite crystals totally covered by a lustrous, brilliant, colorful coating. Something different!
Vekol Mine, Sif Vaya area, Vekol District, Tohono O'odham Indian Reservation, Pinal County, Arizona  USA

Specimen size: 6.5 × 5.1 × 2 cm = 2.56” × 2.01” × 0.79”

Specimen size: 7 × 4.5 cm = 2.76” × 1.77”

FA27: A colorful and slightly iridescent Andradite Garnet from an uncommon locality. A good classic which is hard to find.
Stanley Butte area, Stanley Butte, Stanley District, San Carlos Indian Reservation, Graham County, Arizona  USA

Specimen size: 8.5 × 7 cm = 3.35” × 2.76”

Specimen size: 6 × 5.8 × 5.4 cm = 2.36” × 2.28” × 2.13”

FG90: Amatitlan gave the largest doubly terminated Amethyst crystals in the world. Unfortunately most of them were damaged with broken or significant dings at the top of the crystals. Just a few specimen were saved in good shape. Again, Martín was in the right place at the right time and luckily he got a very esthetic one without significant damage. Plus this specimen has two main doubly terminated crystals joined by other smaller crystals. As you can see in the photo the specimen looks great!
Amatitlán, Municipio Eduardo Neri, Guerrero  Mexico

Specimen size: 9 × 8.8 × 6.2 cm = 3.54” × 3.46” × 2.44”

FC37B8: Really huge (for the locality) Topaz, with some other interesting things: the color is more 'chocolate' than usual; the transparency is better than usual; and it shows a curious inclusion, probably by sandstone, in its center, very visible due its high transparency. One of the best for this locality, in my opinion.
Tepetate, Municipio Villa de Arriaga, San Luis Potosí  Mexico

Specimen size: 4.2 × 3.3 cm = 1.65” × 1.30”

FC91: Between orange and reddish this manganoan Adamite shows an unusual agreeably color. Great luster as well.

Specimen size: 8.5 × 7 × 3 cm = 3.35” × 2.76” × 1.18”

FJ46: Calcite collectors from Spain have on their mind a particular specimen: the "nailhead" Calcite from Mina Julia in Bilbao. Found long ago and no longer available, this particular specimen would satisfy the most demanding collector for its perfection, size and good display.
Julia Mine, Barrio de la Peña, Bilbao, Comarca Gran Bilbao, Vizcaya / Bizkaia, Basque Country (Euskadi)  Spain

Specimen size: 10.5 × 6 × 4.5 cm = 4.13” × 2.36” × 1.77”

Specimen size: 12.5 × 10.5 × 6.5 cm = 4.92” × 4.13” × 2.56”

FX96: In the past one rich find was made in the south of France. Not too well know, this find gave excellent gemmy Calcites comparable to the best ones from Dalnegorsk. Martín was in the right place at the right time and he got this top sample from this exciting find. Perfect, gemmy with great luster and good disposition on its matrix. Neat!
Pau, Pyrénées-Atlantiques, Nouvelle-Aquitaine  France

Specimen size: 9.6 × 5.8 × 4 cm = 3.78” × 2.28” × 1.57”

FD6B9: The Carlsbad twin name came from the Carlsbad locality in the Czech Republic. This Orthoclase also came from this locality and "guess what?": it is twinned by the Carlsbad law. A "type locality twin" from an old glorious European locality.
Karlovy Vary (Carlsbad), Karlovy Vary District, Karlovy Vary Region, Bohemia  Czech Republic

Specimen size: 6 × 3.2 × 2 cm = 2.36” × 1.26” × 0.79”

Esiva, Maromby, Amboasary District, Anosy Region  Madagascar

Specimen size: 3.4 × 2.6 × 0.5 cm = 1.34” × 1.02” × 0.20”

FQ33: A powerful Elbaite. Huge size and doubly terminated (the photos show the details of both terminations) is the start. The "piece de resistance" is the color: a very agreeable gemmy green. It has much better quality, luster and transparency than other specimens from this locality.
Otjua Mine, Otjua Farm 37, Karibib District, Erongo Region  Namibia

Specimen size: 9.6 × 4.4 × 2.4 cm = 3.78” × 1.73” × 0.94”

Tsumeb Mine, Tsumeb, Otjikoto Region  Namibia

Specimen size: 9 × 7.9 × 4.3 cm = 3.54” × 3.11” × 1.69”

FC56: A major specimen. Gartrellite is a mineral species that was recently discovered (1990) and its presentation up until now is not that great under common esthetic standards. Usually it is presented as dull crusts of fine-grained coatings, cryptocrystalline or as incrustations, so basically not beautiful. One specimen from Oliete's collection was labeled as Arsentsumebite, but I was suspicious that it wasn't. I ordered a double X-ray and difractometry test and the result was Gartrellite: bingo! This particular specimen is probably one of the world's nicest Gartrellite and it is shown for first time to the mineral world in this update. Gemmy minor Mimetites are also present, completing a world class specimen.
Tsumeb Mine, Tsumeb, Otjikoto Region  Namibia

Specimen size: 6 × 4 × 3 cm = 2.36” × 1.57” × 1.18”

Specimen size: 6.5 × 1.7 × 2 cm = 2.56” × 0.67” × 0.79”

FD16: Esthetic combination of Rhodo and Quartz.
Pachapaqui mining district, Pachapaqui, Aquia District, Bolognesi Province, Ancash Department  Peru

Specimen size: 6.5 × 5.5 × 3.5 cm = 2.56” × 2.17” × 1.38”

FR56: Nice form (again) in this brilliant Hübnerite with Quartz. A little bit reddish color and, as is usual for Hübnerite, bright red on the corners when seen with a strong back light. Totally damage free but with some contact on one corner.
Huayllapon Mine (Huallapon Mine), Pasto Bueno, Pampas District, Pallasca Province, Ancash Department  Peru

Specimen size: 5.7 × 3.9 cm = 2.24” × 1.54”

FR54: Doubly terminated Rutile, complete on all sides, with a gem-red color (visible when viewed with intense light from the back). Its elongated shape is also quite unusual.
This type of Rutile has not been seen on the market for a long time.
Dom Bosco, Miguel Burnier, Ouro Preto, Minas Gerais  Brazil

Specimen size: 6.2 × 0.3 × 0.3 cm = 2.44” × 0.12” × 0.12”

FK76: Doubly terminated (although the left termination it is not sharp) pretty transparent, an excellent representative of the species. Photographed on page 179 of the Spanish mineral book: 'Minas y minerales de Iberoamérica'.
Itinga, Jequitinhonha  Brazil

Specimen size: 4.5 × 1.6 × 0.7 cm = 1.77” × 0.63” × 0.28”

FM17: Elbaite of the type colloquially referred to as "black cap" due to its very dark upper termination.
Recrystallized at its bottom, with good transparency and shape.
Virgem da Lapa, Jequitinhonha, Minas Gerais  Brazil

Specimen size: 6.5 × 1.8 × 2 cm = 2.56” × 0.71” × 0.79”

FZ47: Lustrous Topaz 'saramenha' ('imperial' in Spanish language) with sharp undamaged tip and good transparency and color.
Ouro Preto, Minas Gerais  Brazil

Specimen size: 4.6 × 2 cm = 1.81” × 0.79”

FY53: Gem single crystal of Cassiterite, complete in all sides (but with a contact on its back) pretty sharp and huge.

Specimen size: 3.6 × 3 × 2.8 cm = 1.42” × 1.18” × 1.10”

FH27: Extremely brilliant (for the species) large crystal size, from a no longer productive mine. So, something not easy to find today, and of course much better than Zinkenites form other localities.
San José Mine, Oruro City, Cercado Province, Oruro Department  Bolivia

Specimen size: 6.7 × 4.4 × 3.3 cm = 2.64” × 1.73” × 1.30”

FA77: Again, something extremely unusual from Martín. This well formed Chalcocite which is aerial on the Calcite matrix comes from Chile. On Oliete's label the location is written as being Chuquicamata. After hard investigations about Chilean mineral localities I'm able to tell that it must came from Copiapó and I'm also able to say that I have never seen anything similar in my life and I'm sure that not too much other people have either. Well, it is good, sharp and extremely original.
Copiapó  Chile

Specimen size: 8.5 × 7 × 3.6 cm = 3.35” × 2.76” × 1.42”

FZ16: As a collector specimen this Atacamite shows something different from other specimens. In this particular case it is the unusual presentation: it is on top of Agate, with a wonderful contrast between the lustrous green Atacamite crystals and the banded grey Agate. Different!
La Farola Mine, Cerro Pintado, Copiapó, Atacama  Chile

Specimen size: 9 × 7 cm = 3.54” × 2.76”

FY26: Classic but perfect, gemmy and esthetic. No faults on the specimen!
