TE67AJ2: Rosette aggregate of flattened and very well defined Volborthite crystals that are bright with a deep olive green color. With a very sharp, doubly terminated Azurite crystal on the Volborthite that we must consider a rarity. The Milpillas Volborthite samples are probably the world's best for their quality, luster, and crystal size, and they are considered a new standard for this species. An excellent miniature, different from other well-known Volborthites.
The sample has been noted and photographed in the monograph 'The Milpillas Mine' of the ‘Mineralogical Record‘ magazine on page 620 in the volume 52, number 5, September-October 2021
