On this page we have shown a good representation of the specimens from the Joaquim Callen's Photo Gallery that, because of their quality, rarity or interesting locality, we wish to maintain on our web site as reference specimens although they have been sold.

When Jordi offered me a corner on his web page to publish photos of the pieces that I choose I found it an excellent idea. It goes without saying that the project made me very enthusiastic immediately.

It is my intention to show, through my photographs, my point of view of the beauty of minerals, and I hope to add to that a point of charm, that touch of magic that minerals awaken in all those who view them with delight and admiration.

An American classic coming from a mainly forgotten mine, the Anselmo mine. The crystals are almost completely covered by a thin crust of Quartz but in some places where there is no Quartz you can see their excellent color.

 

Anselmo Mine, Butte, Butte District, Silver Bow County, Montana
USA


Specimen size: 4.8 × 4.1 × 3 cm = 1.9” × 1.6” × 1.2”

Very good geometry, a floater, doubly terminated and with a white phantom inside. Its color is not very intense but I like classics, and for obvious reasons I like this classic.

TB91AG1
Large crystals of amethyst, different than the classic amethysts of Las Vigas, with thicker and slightly tapered crystals and zoned color, very intense in the first generation of the crystal and colorless or white in its last growth phase. A classic of the past from the collection of José Luis Vallecillo.

La Gardette is a mythical name. That small mine located in the middle of the French Alps has offered and continues to offer some of the most elegant Quartzes in the world. A beauty as fascinating as the place where they are found.

MB57AI6
A sample that has the special attraction of being a German classic, a Baryte that forms a parallel aggregate of very sharp thick tabular crystals that are partially coated by disphenoidal Chalcopyrite crystals with a tetragonal shape, with very well defined faces and edges and very intense brightness.

Silver from Kongsberg is obviously part of the history of mineralogy but also of European history. On this sample the Silver has grown forming delicate arborescent aggregates of small octahedral crystals included in Calcite and on a rocky matrix.

Dalnegorsk is one of those mineral localities that is always offering nice surprises to the collector as has happened with this thick tabular Calcite crystal that has the exquisiteness of a very sharp hexagonal form and the aesthetics of the added group of smaller Calcite crystals.

ME51AG6
Scorodites are known in the Oumlil Mine but have recently been found there in very individual crystals and associated with Karibibite. This is the best piece that we got from this association in Munich 2017. Who knows if we will see more in the future, the only certain thing is that now and here we have this one.
This specimen was photographed and published as a novelty at the 2017 Munich Show in the magazine ‘Le Règne Minéral’ Nov/Dec 2017, number 138, page 35 and for the magazine ‘Mineralien Welt’ on page 71 of number 1/2018

MQ28AG8
Grandidierite is one of the great myths of mineralogy, especially in the field of rare species. It was believed that we would never see more Grandidierites of such quality as those that exist in the great museums of the world, especially the museums of Paris, but for a couple of years in a little-known Madagascar site excellent Grandidierites have been appearing, some of them of as great quality as the famous specimens that appeared in the past.
This specimen was photographed for the ‘Munich 2017’ section of the magazine ‘Mineralien Welt’ and appears on page 70 of number 1/2018, and for the magazine ‘Mineralogical Record’ on page 338 in the volume 49, number 2

From a new location not known until now come these limpid citrine Quartzes with an extraordinary color. Many of them have small dings, this one in particular also has some, but in any case its color is so beautiful that I think it can be forgiven.

MC93AG6
In 2017 in the N'Chwaning I Mine some manual work for the extraction of collector’s specimens was initiated. This colorful Shigaite in Rhodochrosite is a good example of the result of this work. The good form of the crystals that are very aerial, their transparency, color, brightness and perfection are the hallmarks of this piece.
This specimen was photographed and published as a novelty at the 2014 Munich Show in the magazine ‘Le Règne Minéral’ Nov/Dec 2017, number 138, page 29

Yes, the crystals of Wulfenite can also be very large as shown by this giant from Tsumeb, partially coated with crystals of Calcite and iron oxides.
The collector René Hubin from Neupré, Belgium had the luck and the success of obtaining this "monster" and us we were happy to buy it from him!

The Cadmium-rich Smithsonite variety is an uncommon find at Tsumeb so it is a pleasure to be able to photograph this druse of rhombohedral crystals with very well defined faces and edges and displaying a delicate orange color, due to the presence of Cadmium.

What about the Golds from Serra do Caldeirão? Much of what happened there in 2015 is well explained in this FMF thread: An opportune harvest of Gold in Serra do Caldeirão claims, Brazil
This specimen has an excellent quality-price ratio given the good definition of the terminal faces of the crystals that show a kind of "hopper" growing.

ML49AI6
Brazilian Euclase is a classic that must not be missing in any collection and, as a magnificent example, here is this parallel growth of very sharp crystals, colorless with an extraordinary luster and of a considerable length for the species.
The sample is from the Uwe Niemeyer collection (Germany) whose label we’ll send to the buyer.

TB87AH3
The luster, the finesse and the definition and the length of its crystals should be enough to consider the sample on a rank of very good quality, and more if we add an excellent esthetic profile that is especially photogenic.
This specimen was published on the Mineralogical Record´s web page, in the ‘What's New’ section, report 49, May 7, 2018 edition.
