The Mystery of Moonstone |
||
|
Rainbow Moonstone is a white or clear colored stone with an
opalescent "fire" (called schiller or adularescence) in its
heart that moves and changes as one's viewing position
changes. The fire of Rainbow Moonstone, and the shimmer in
regular Moonstone, is caused by two different varieties of
feldspar that have grown together in a matrix that reflects
light differently depending on one's viewing point. Because Rainbow Moonstone is natural, rather than man-made, each stone has it's own personality. Some stones have a blue fire, while others have a yellow or greenish tint. There is no better or worse with regard to the fire. As with other stones like Turquoise, beauty is in the eye of the beholder. Rainbow
Moonstone is not related to Opal, as people sometimes think.
In fact, Moonstone is a member of the Quartz family of
minerals. It is technically a variety of labradorite feldspar,
crystalline in nature. Moonstone is mined in South India and
Sri Lanka, while limited deposits of Rainbow Moonstone are
also found in Madagascar. |
