Andorite (very lustrous!)

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, HIGHLY LUSTROUS crystals of the rare lead, silver, antimony sulfosalt Andorite which are associated with thin, metallic, prismatic crystals of the rare sulfide, Zinkenite. 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 association specimen of these rare mineral species. This specimen was valued in the inventory at $1200 for the greatquality, and considering that no new specimens are coming out, the value of these pieces will surely increase as the part of the mine that produced these specimens is mined finished by all accounts.
