Classic locality

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.
Main crystal: 2 mm.
Found in ca. 1970's.

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.

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.

Very aesthetic specimen of fluorite. It shows the cubic shape, with polysynthetic growths on faces. The color very uniform, a delicate violet tone, with geometric zoning on edges, more intense. 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.

Size: 5.2 x 3.5 x 3.5 cm.
Main crystal: 2.4 cm.
Found in 1980's.

Very aesthetic globular aggregates of smithsonite, with an apple green color, translucent, accompanied by several lanceolated sharp and transparent hemimorphitecrystals. In a vug of the goethite matrix. Smithsonite specimens from this Mexican mine are highly appreciated by collectors. From the 8th level of this mine.

Size: 8 x 6 x 4.5 cm.
Main crystal: 1.3 cm aggreg.

A nice specimen of delicate purple to violet creedite is from the early 1980's find in Santa Eulalia. Complete, brilliant, the specimen features gemmy crystals to almost 1 cm. Purple creedite specimens are unusual in the market.

Size: 7 x 6.5 x 3.3 cm.
Main crystal: 1 cm.
Found in ±1980.

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.

Fluorescent under long wave UV

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

Globular aggregates of mimetite crystals, with an intense luster and yellowish honey color. It is a floater and it back side there are some spherical vugs those are difficult to interpretate. Take a look. An aesthetic miniature from this famous Mexican mine.

Size: 4,3 x 3,3 x 2,3 cm.

Size: 3,9 x 2,5 x 2,0 cm.

Botryoidal aggregates of smithsonite, with a good green color, showing possible rhombohedral forms. If we look carefully we can see several crystals of this zinc carbonate forming this forms. We emphisize on the quality of this specimen.

Size: 7,8 x 5,4 x 4,5 cm.
