Baryte w/ Magnesite coating (rare) Kay Robertson Coll.

Item Description

RARE and rich barite from an obscure Austrian locale. Three sides of the mounded sculptural matrix are festooned with glassy, colorless, tabular barite spearpoints. The striking larger stepped-growth clusters, to 1.7 cm, look like flocked Christmas trees! The whiter color is due to preferential coatings of magnesite. Ex Kay Robertson Collection # 2582 and acquired from the Lindemann Collection in June, 1962. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). A rare, rich and desirable older classic.
