Item Description

From the great find of November 2004. Andorite is lead, silver, antimony sulfosalt and was named for the Hungarian mineral collector Andor von Semsey (1833-1923), who holds a remarkable distinction for having two mineral species named after him (andorite and semseyite). I personally acquired the entire lot of ALL the good crystals that came into the U.S. over the last few months and which many experts considered to be such a significant find, that it completely redefined Andorite as a crystallized species. This mine at Oruro dates Spanish mining as far back as the year 1595 and was mined by Incan Indians for several centuries prior. In all the years of mining, these are undoubtedly, the worlds finest Andorites extant! These specimens were extracted from the same vein system worked by the father of Bolivian mineralogy, Federico Ahlfeld. Ahlfeld worked the San Jose mine and Itos mine (the other significant andorite locality at the same mountain in Oruro) when the mines were used predominantly as a major sources of tin to the United States during WWII. The best examples of the species have come from Bolivia. This specimen consists of layered, steel-grey, crystals of the rare lead, silver, antimony sulfosalt Andorite. The particular crystallization on this specimen is reminiscent of the great old classic specimens from about 60 years ago, which is sometimes referred to as the "flower"-like growth. The piece is nearly crystallized all the way around, and despite a contact on the side, is still in superb shape overall. It is very difficult to find any samples of this mineral on the market today, and until very recently, the locality had not produced specimens in MANY years. A wonderful opportunity to own a superb specimen of this rare mineral species. This specimen was valued in the inventory at $2,000, for the quality, crystallization and the fact that it's a top notch thumbnail Considering that no new specimens are coming out, the value of these pieces will surely increase as I'm told that the part of the mine which produced these specimens is finished.
