Dioptase on Smithsonite

80 x 52 x 39 mm overall
with 1 mm Dioptase crystals

Gemmy bright-green crystals of Dioptase to 1 mm are heavily scattered on a knob covered with 1 mm crystals of sparkling white Smithsonite. This is a rare association from this famous, now closed mine. This fine old specimen dates to about the mid 1960s, when this collection was assembled. No damage.

ex. Paul Edwards collection.
