Boracite

Boracite can be identified by its crystal habit, color, associations, locality
and its high hardness. In industrial applications, Boracite is used as an
ore of Boron for boric acid and Borax (a cleaning agent and useful industrial
chemical). Although it has nice color, clarity and the hardness necessary
to be used as a gemstone, Boracite is rarely cut for this purpose. Probably
because it is slightly soluble in water and ordinary wear dulls its surface.
Still, it is a very attractive gem among collectors. |

A variety of Boracite found at Strassfurt, Germany is a fibrous form named
Strassfurtite after the locality. |
