Dioptase - Magma Mine, Superior, Arizona
Measurements: 5.3 x 3 x 2.2 cm.
Ex: Kay Robertson Collection.
A beautiful rare-locality specimen, with the added bonus of having some lovely provenance! Kay was a famous collector who advocated for the love of minerals over their monetary representation. This specimen has an amazing color and a beautiful luster with a contrasting matrix, which seems to be at least partially Chrysocolla, which is adorable.
