I’ve posted excellent new specimens from the John S. White quartz collection, representing many different phenomena of quartz crystallization, also from a great diversity of localities and mineral environments.
I’ve added more gorgeous specimens in this latest update from the John S. White quartz collection.
I’ve added some super specimens from Mount Malosa in this new Malawi Update. These include excellent crystals of aegirine, arfvedsonite, smoky quartz with epididymite inclusions, microcline and zircon. Under shortwave ultraviolet light, the microcline is a striking deep pink-red colour, and the zircons exhibit various hues of yellow.
