Item Description

A nice association specimen from the historic find in November 2004. Andorite is a rare and sought after lead silver antimony sulfosalt. The species 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. in 2004, which many experts considered to be such a significant find, that it completely redefined Andorite as a crystallized species. The San Jose Mine is well documented by the Spanish as far back as the year 1595 and was mined by Incan Indians for several centuries prior. This piece is a group of classic, steel-grey, lustrous layered, striated metallic Andorite crystals associated with rare prismatic Zinkenite needles on the back. I love the three-dimensional quality of the piece, and despite the fact that it's rough around the edges, it's still well-crystallized and a fine quality example of the species. 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 decent quality display specimen with the rare Zinkenite association. Valued at $500.
