From the new 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). 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. The piece is a "classic," lustrous, steel-grey, multi-layered crystal group of good size and quality. The specimen is associated with minor prismatic Zinkenite crystals. It is a very aesthetic and showy specimen, and is in good condition for this material, with only one spots on the bottom where it detached from the pocket wall, and is not fresh damage, but happened long ago underground. It displays amazingly well from one side showing virtually no damage. 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.
