Stibiconite ps. After Stibnite (classic locale) ex Kay Robertson Coll.

Item Description

An aesthetic diverging cluster of tan terminated pseudomorphs of stibiconite after stibnite crystals. All of terminations are pristine and only one broken pseudo is noted. Complete all-around. The broken crystal is mostly out-of-sight in the preferred display views. Stibiconite after stibnite specimens from the historic old silver mines at Catorce are a classic and desirable Mexico species. Ex Kay Robertson Collection # 4242 and acquired in 1965. Kay's label is incorrect. These striking pseudos are from Catorce. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record).
