Dioptase (Ref: P307)

Tsumeb, Namibia
32mm x 25mm x 20mm
$3000
Fine quality large Dioptase crystal on a matrix coated by blueish Dolomite and white Calcite. The main Dioptase is 1.4cm tall, sharp, and highly lustrous. Green Duftite can be seen on small areas of the matrix where the Calcite and Dolomite are not present. Really fabulous thumbnail with a different look than most. Purchased by Jack Crowley from Al McGuinness in 1983 (his collection number is painted on the back).
