Measurements: 38 x 35 x 25 mm
Description: Gemmy, small calcite crystals sit on gemmy dioptase
crystals which, in turn, sit on a matrix of
(?)quartz and calcite. The
dioptase has a lovely bottle-green colour, more beautiful than in these
images, and the specimen has a sparkle to it (seen when held in light), another
difficult feature to portray in these images.
There is damage to some of the dioptase crystals on the edges of the
specimen. The specimen displays well on a flat surface.
Weight of Specimen: 41.3 g
Chemical Composition: Cu2+SiO2(OH)2 (dioptase)
Hardness on Mohs Scale: (dioptase) 5
