Very rich specimen formed by aggregates of prismatic crystals of mimetite, transparent, forming sheaves and divergent growths. The yellow-orange color and luster make them stand out on a matrix with romobohedral calcite crystals. A classic from the 1960s to 1970s.


Size: 5.5 x 3.7 x 3.3 cm.

RM2555   Natanite and rhodochrosite
More photos

Natanite is a rare iron and tin hydroxide. It shows octahedral crystals truncated at their vertices by the faces of the cube. In this aesthetic specimen we can observe some very well defined, transparent crystals with an intense yellow color. They stand out on a matrix with brilliant rhodochrosite crystals. An exceptional sample for the species and the locality. Although the best specimens of natanite have been found in the Potosí mine, the type locality for the species is in the former Soviet Republics of Kyrgyzstan and Tajikistan.


Size: 3.4 x 3.2 x 1.5 cm.
Main crystal: 1 mm.

RM2468   Calcite
More photos

Group of very acute scalenohedral calcite crystals, well defined and with a brown colour due to inclusions. Thanks to some of these crystals that show exfoliation, we can observe that it has been formed in the final stages of their growth. From the A. Trigo collection (Mataró).


Size: 6.6 x 4.5 x 4.2 cm.
Main crystal: 1.8 cm.
Found in ca. 1996.

RM1722   Manganocalcite with fluorite, galena and pyrite
More photos

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.


Size: 8.7 x 7.5 x 3.5 cm.
Main crystal: 10 x 8 mm.

Col. J.M. Manchion (Barcelona) - No.420 (Kucera, 1988)
Fluorescent under long wave UV

RM1670   Rhodochrosite
More photos

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.


Size: 6.8 x 5.6 x 3.8 cm.
Main crystal: 5 x 1 mm
