This small specimen shows a rosette-shaped growth of flattened Volborthite crystals on matrix; the rosette is very sharp and deeply colored.
The sample has been noted and photographed in the monograph 'The Milpillas Mine' of the ‘Mineralogical Record‘ magazine on page 619 in the volume 52, number 5, September-October 2021

EV67AC1: Volborthite with Malachite

Volborthite was the new sensation in the Tucson Show 2015 as well as in Ste. Marie, but the number of them seems to be somewhat limited.
The Milpillas ones are without doubt the world's best for their luster, shape, good contrast with the white clay matrix and the crystal size of the best ones, so all together these are a new standard for this species. We are proud to offer this one which has a very reasonable balance quality / price.
