Fluorite (calcium fluoride), historically called Fluorspar, has been
used in carvings and decorative objects for hundreds of years, but the
availability of faceted pieces is a relatively new development. Not
readily useable in jewellery due to its softness, and perfect cleavage
in four directions, it is primarily a collector's gem. Faceting this
material presents considerable challenges, but well cut and polished
gems can be very bright and appealing.
It is said to increase concentration. |
