Labradorite
is a variety of Feldspar, originally named after being discovered in
Labrador, Newfoundland (Canada). It is found in several countries,
although known as Spectrolite in some locations, due to the many
brilliant spectral colors of "flash" or "schiller" which can be seen
when light is reflected from it. The several areas of Madagascar where
Labradorite is mined provide perhaps the largest concentration of this
gem mineral found on the planet. Madagascar produces the world's best
quality of Labradorite.
