Volborthite with Brochantite

Excellent platy crystal rosettes of dark olive green Volborthite forms a very rare combination with acicular turquoise green Brochantite crystals, from the relatively recent (2014-15) find at Milpillas mine at Cuitaca in Sonora, Mexico.  Overall, the rosettes of Volborthite crystals measure to 1.4 cm on snow white 'Dickite' covering a light grey Limestone.  Volborthite from Milpillas mine is regarded as probability the best for its species in the world.  The Brochantite forms as very fine, hair-like acicular crystals around the base of the Volborthite, in long delicate sprays.  Despite being so fragile, the Brochantite is fairly well protected by the Volborthite.  A superb small miniature of Volborthite with Brochantite from the Milpillas mine in Mexico.
