Tincalconite ps. Borax and Hanksite (Type Locality for both) Al Ordway Coll.

Item Description

An excellent, large, and sculptural combination specimen of rare species from Searles Lake, California and the Al Ordway Collection # 2582. Intergrown, sharply terminated, blocky borax crystals are pseudomorphed by snow-white tincalconite. A bit of translucent, gray hanksite is well-placed on the front. Hanksite is a rare sulfate and tincalconite is a rare borate. Searles Lake is the Type Locality for both species. This is a striking, very fine, complete all-around and nearly pristine combination example of these rare species. Self-collected in 2003, according to the label. This is as fine a piece a sany I have seen recently, and one of the larger and more robust single crystals. Valued $750-1000
