Black star diopside is generally a blackish or blackish green color;rarely a definite green. It is, of course, cut into round or oval cabochons which are generally biconvex with a roughly shaped, unpolished base. The star characteristically has a fore rays, two of which are straight, while the other two, not at right angles to the first pair, look slightly wavy (the crystal does not, in fact, have fourfold symmetry). Sometimes, oriented acicular (need like) surface crystalline inclusions are clearly visible, especially from below.
DISTINCTIVE FEATURES: Star diopside has only binary symmetry, and the star has four rays, rather than six like other star stones. When the gem contains conspicuous need like crystals (of magnetite) it is easily attracted by a magnet.
OCCURRENCE: Star diopside comes mainly from India. Hence the name Black Star of India.
ANCIENT HEALING PROPERTIES: Brings necessary tears, heals trauma, aids regression, crying stone
