A hard silicate of alumina in rhombic crystals of a colour varying from pink to violet. More rarely, it may be red or green. Its main quality is its exceptional fire.
If you are thinking of buying andalusite, you should choose a specimen in its original shape, flawless and of as deep a hue as possible. The price of this stone rises steadily, but never in leaps and bounds.
It is found in Brazil, Ceylon and Madagascar and is mostly used for the creation of exclusive jewelry for a clientele of connoisseurs.
