Classic locality

Specimen of native silver from this more than classic Mexican locality such as Batopilas. This specimen shows numerous herringbone-patterned, arborescent and skeletal silver aggregates formed by crystals spinel-twin, very elegant and with luster and colour. They are disposed aerially on a matrix with calcite. Finding specimens of this quality and size (and price) from this mine is not easy at all. It belongs from a former Austrian collection.

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.

Main crystal: 1.8 cm.
Found in ca. 1996.

Col. Joan Astor,

Colorful specimen of arsenatian vanadinite crystals, in aggregates of hexagonal prismatic crystals, with hopper cavities on the pinacoidal faces. Intense shine, orange to brown, with zoning, transparent to translucent crystals. They stand out on a white matrix of calcite. An excellent specimen of this Mexican mine.

Classic locality

Rich group of sharp arsenical vanadinite crystals, with curved faces prisms, barrel-shaped and many of them doubly terminated, with the characteristic color of this variety. Two generations of crystals are observed, those of greater size opaque and with a brown tone, on which a second generation of transparent toasted honey tone crystals has grown, all very very brilliant. A pleasure under the magnifying glass. This mine is also known as Apex.

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.

Main crystal: 1 cm.
Found in ±1980.

These specimens of wulfenite with the chocolate brown to orange tone are very appreciated by collectors and very difficult to see today, unless they come from former collections with tradition. This specimen shows a large group of tabular crystals, very brilliant and translucent, few small nick that does not affect the aesthetics of the specimen. A classic piece.

Classic locality

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.

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

Very rich specimen formed by numerous prismatic crystals of wulfenite, with orange color. They are brilliant and disposed on the matrix. A specimen more than aesthetic historical, fine quality and from a classic Mexican locality.

Main crystal: 4 x 3 mm.

Very rich specimen formed by numerous prismatic crystals of wulfenite, with orange color zoning. They are brilliant and disposed very aerially on the matrix. It is accompanied by calcite, which in the back part of the specimen partially covers the crystals of wulfenite, with small aggregates of yellowish arsenatian vanadinite crystals, curiously close to pyromorphite. We will send the analysis to the buyer. A specimen more than aesthetic historical, fine quality and from a classic Mexican locality.
