Item Description

A beautiful display piece of vibrant greenish-blue colored Smithsonite on matrix from an unknown locality in Sardinia (possibly the Monteponi Mine). These complex semi-spherical crystals measure up to about 4 mm, but for the size, the saturation is superb! This is rare material, and while doing research I couldn't find a piece that matched this one exactly, so I have to believe it came from a small find. Ex Kay Robertson Collection (#9328). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record).
