Moonstone

A translucent variety of feldspar with a chatoyant quality, that is to say, having a changeable, undulating pearly lustre. It is either colourless or bluish-white and when cut en cabochon shows bluish gleams

Moonstone is not excessively expensive and being moderately rare is a good investment. The finest stones are those of a slightly bluish tint, reminiscent of the colour of the moon, hence the name.

It comes mainly from Burma, Ceylon, Madagascar, Brazil and to a lesser extent Norway and Switzerland.
