Rhodochrosite on Quartz w/ Pyrite (RARE combo) Robertson Coll.

Item Description

A VERY RARE, old, rich and sculptural combination from this obscure mining district in Sonora. Rosettes of tannish-pink rhodochrosite disks richly and attractively coat the front of the dramatic mounded quartz crystal plate with striking accenting large crystals across the top of the piece. The large quartz is 1.8 cm. A super accessory is the sharp, striated, 1.7 cm pyrite cube hidden on the back. MINDAT lists only pyrite of the three species for the locale. The piece was shown to respected Mexican specialist, Dr. Pete Megaw, who said the attribution is probably correct. "Mindat is only as good as its sources and there do not seem to be many folks knowledgeable on that district." Ex Kay Robertson Collection # 1382 and acquired at the Long Beach Show in 1959. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien-Welt" November-December 2017). A MUST for the species or the locality collector!
