{"product_id":"dioptase-16","title":"DIOPTASE","description":"Bright emerald green Dioptase crystals up to 0.9 cm long richly coat the top surface of a Calcite matrix whose top is crystallised in the rhombic habit.  Dioptase is a copper silicate and on this miniature, forms crystals down to sub-millimetre in size.  Such small crystals allow more light to pass through and so appear a more bluish green; more the colour often seen of Dioptase when photographed but not colour corrected!  The Dioptase varies between semi-transparent and translucent and all crystals have a bright glassy lustre.
