Description:
The feldspar group, to which adularia belongs, is very important in industry in the manufacture of many every-day products, both for domestic and industrial use. This group includes amazonite, labradorite, orthose, albite amongst others, some of the oldest gemological materials used by Man. Here we show a beautiful specimen of adularia, also known as moonstone, formed by various interpenetrating crystals and of an extraordinary luster. |
