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.
