Group of prismatic fluorapatite crystals, with faces of the prism and the hexagonal dipyramids. The transparence and brilliance areexcellent and the yellow color is very intense. This specimen was photographed in some books that Joan Astor published in issuu [online page 86]. It is accompanied in the matrix with hyaline opal aggregates. It was acquired in 1980 from Bailey Minerals (Ángel Jesús Talabán García, Segovia 1942-Madrid 2007). A very aesthetic and good size piece.

Size: 8 x 5 x 4 cm.
Main crystal: 2 cm.

Excellent brilliance, transparence and very well defined faces and edges. An exceptional piece from Santa Eulalia and the Joan Astor collection, acquired by this great Catalan photographer and collector at the EXPOMINER Barcelona mineral show in 1981.

Mimetite Mexican specimens from Ojuela mine (Durango) and Potosí mine (Chihuahua) are the best considered by collectors. Currently those of Ojuela abound, but those of Potosí, with isolated crystals and globular aggregates like this specimen, are more rare to see. They stand out for their intense yellow-green color in some area and on a matrix of rhombohedral crystals of calcite.

Size: 5.6 x 4.7 x 2.3 cm.

Very, very aesthetic specimen, unusual, showing two globular aggregates of smithsonite, colorless, transparent that let us see a whitish crystal aggregate core, with very curious growth. They are accompanied by small crystals of the same species in the form of globular grains. To give a touch of color and quality, several aggregates of olive green adamite crystals, visible terminal faces, bright, translucent and sprinkling the goethite matrix. It is an exceptional and rare old material from the Manchion Collection. Probably this specimen comes from the Palomas Oriente area of the mine. Pure aesthetics... With the label from Manchion Collection.

Very esthetic specimen formed by some groups of prismatic crystals of adamite, contrasting on a matrix of goethite. The crystals have a very uniform yellow color, with transparency, with very well defined faces and edges and forming rosettes. We can also observe isolated doubly terminated crystals and some almost colorless. A pleasure under the loupe magnifying glass. Good size.

Group of crystals of adamite, which show a geometric color zoning from yellow to violet due to the presence of manganoan adamite, a variety of adamite rich in manganese. Thios cation gives to these specimens a violet to purple core. Very bright, defined and with transparence that allows us to see this species. Nice and aesthetic specimen.

This specimen of legrandite shows us a group of sharp crystals of this rare zinc arsenate, with an intense orange-yellow color. It is common that some crystals appears fractured, but in this sample there are several perfect prismatic crystals, undamaged, brilliant and with an incredible transparence. I personally like isolated crystals and this piece is one of them. Good size, brightness and aesthetics, very representative for the species. Accompanied by elongated smithsonite white crystals.

Very esthetic specimen formed by numerous aggregates of crystals of calcite manganoan, very bright, transparent to translucent, forming globular groups very well set on the matrix. They present a slightly pinkish tone due to the presence of Mn. Extremely fluorescent under LW-UV, with a spectacular pink to red color. They are accompanied by small octahedral cubic crystals of colorless and transparent fluorite. In a matrix of bright crystals of pyrite, sphalerite and galena. An exceptional piece.

Very rich specimen of rhodo, formed by several gemmy, rose-red elongated rhombohedrons covering the matrix on this fine, fine quality sample from the famous 1970s and 1980s finds at Santa Eulalia. Observed under magnification we can see that elongated faces are semidull and terminal rhombohedrons are brilliant and transparent. Color is really good. Not easy to find in the market specimens with this quality.
