Indicolite is the rarest and most valuable member of the tourmaline mineral elbaite. Indicolite is one of the rarer varieties of elbaite. It is generally azure or deep blue although it may sometimes also have discernable green tones too, even the cat's eye green as shown above.

Indicolites show different colours depending on the angle that they are viewed from. This phenomenon is known as pleochroism. Craftsmen who cut gem quality indicolite always pay special attention to bringing out this beautiful effect to its best advantage, thus creating billiant colors. All the characteristics make it very desirable to gemstone collectors as well as those who wear it as decorative jewellery.
