Andalusite
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.
