Main crystal size: 5.6 x 2 cm

SV740EBB

Druse of Calcite crystals partially covered by pinkish Talmessite, deeper pink in some areas of the specimen, showing coralloidal forms, with darker banded areas caused by manganese oxide stains.
The specimen has been analyzed and we will send a copy of the analysis to the buyer.

SV360TAR

A novelty for 2021: Shinichengite on matrix (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite) that forms small fibrous spheroidal coatings of intense pink color that accompany spheroidal growths of orange-brown Bultfonteinite.
The specimen has been analyzed and we will send a copy of the analysis to the buyer. If you wish to delve deeper into the species and parageneses of this mine, you can consult the article by Menor-Salván, C.; Ottens, B.; Richard, E. “Rare borate minerals from the Shijiangshan-Shalonggou Deposits, Hexigten Banner, Inner Mongolia, China”.

Type locality Shinichengite

Analyzed

SV210MLH

Complex crystals of Sphalerite, equant, transparent, with very good luster and an intense color, with defined edges and faces, some of them showing polycrystalline growths, on a matrix partially covered by small Quartz crystals, from a skarn deposit with Cu-Pb-Zn enrichment. The specimen is of better quality and luster than what usually appears at this mine.

Shuikoushan Mine, Shuikoushan ore field, Changning, Hengyang Prefecture, Hunan Province, China China (11/2022)

Specimen size: 6.8 x 6.3 x 4.2 cm

Main crystal size: 1.5 x 1.1 cm

SV280MXB

Globular aggregates of rhombohedral Smithsonite crystals with very rounded faces and edges, its yellowish green tones displaying a predominance of the latter, with velvety appearance and satiny luster, dotted with small but very sharp scalenohedral crystals of snow-white Calcite, giving a beautiful color contrast to the specimen. Smithsonite had not been reported from this mine before, so this specimen helps to expand its paragenesis.

Leiping Mine, Leiping, Guiyang, Chenzhou Prefecture, Hunan Province, China China (2019)

Specimen size: 6.7 x 4.9 x 3.3 cm

SV460EFG

Spheroidal aggregates of very shiny Chalcopyrite crystals on a matrix formed by a growth of Calcite crystals in two phases: the first as darker scalenohedral crystals, and the second in the form of coatings of small clearer crystals. On the back, crystals of Chalcopyrite cover practically the entire piece. Comes from a mine which exploits a deposit rich in copper and molybdenum.

Tongshankou Mine, Edong, Daye, Huangshi Prefecture, Hubei Province, China China (03/2022)

Specimen size: 5.6 x 4.4 x 3.3 cm

SV180MBR

Groups of crystals in radial fibrous aggregates composed of Tyrolite crystals, with bluish green tones, arranged on a matrix partially covered by a thin crystalline crust of Theisite. From a Chinese locality, Sanguozhuang, where lead and zinc are extracted, and which is the type locality for 5 new mineral species.

Sanguozhuang mining area, Sanguozhuang, Dongchuan District, Kunming Prefecture, Yunnan Province, China China

Specimen size: 3.4 x 3 x 1.8 cm

SV280MBX

Distinct groups of Veszelyite crystals on matrix, aggregated in sheaf-like habits, each with preferred and parallel orientations, elongated and very sharp, with well defined crystal forms and an intense and uniform color, standing out on a thin crystalline layer of very pale blue Theisite coating the rock matrix, which gives a beautiful color contrast with the Veszelyite crystals. From a Chinese locality, Sanguozhuang, where lead and zinc are extracted, and which is the type locality for 5 new mineral species.
