Mroseite With Tellurite
Bambolla Mine, Moctezuma, Sonora, Mexico (TYPE LOCALITY)
Cabinet, 10.7 x 7.6 x 4.0 cm
This large specimen features numerous fat tellurite crystal clusters to 5-6 mm perched on the edges of a protected vug, lined with drusy quartz - a beautiful and unusually rich specimen. Though there is some damage, there is a lot of material here to make up for that. Moreover, this piece is rich in the rarer species Mroseite, which is present as white cleavage fragments all over the lefthand side of the specimen (per Bill Pinch, Mark Feinglos, and Marcus Origlieri by visual inspection). One of the surprises of 2007 for rarities was the reworking of the famous old Bambolla mine in the Moctezuma tellurium complex for specimens, by several European-led collecting teams. Many specimens were then sold at Munich 2008 and this year in Tucson.
