Description:From the historic find in 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. during this time and 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, the specimens found in 2004 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. The piece features a layered group of classic, somewhat thick, steel-grey, semi-lustrous, tabular crystals of Andorite with an associated "spray" of brownish-grey Zinkenite. The fact this is a 2.5+ inch crystal group is excellent for the species. The piece is not 100% damage free, as you can see from the phtoos, but it's still an aesthetic and showy specimen that I would call somewhat doubly-termianted or at least "multi"-terminated. It is very difficult to find any samples of material mineral on the market today, and until the 2004 find, the locality had not produced specimens in MANY years. A wonderful opportunity to own a great display specimen of this rare mineral species. Valued at $1,250 in the inventory for the sheer size! One of the better pieces of Andorite from San Jose that we have had to offer in the auctions for a while.
