The Gemstone Labradorite
Labradorite is an important feldspar gemstone. It often displays a beautiful iridescent play of colors, which can move as the stone is rotated. Labradorite gemstones usually have a dark base color with metallic-looking color plays of blue, green, yellow, and red. This iridescent effect is commonly known as labradorescence, and is named after this stone. It is caused by internal fractures that reflect light back and forth, dispersing it into different colors.

Labradorite is named after the Canadian province of Labrador, the classic locality of this gemstone. Labradorite is often heavily flaw
ed with internal dark lines and streaks; stones that are clean of flaws are rare. Some stones have a greater labradorescence
effect then others, and a greater play of color increases the value of the Labradorite. A new reddish gemstone popularly called "Andesine
" has recently sprung up on the gemstone market; this gemstone is formed by synthetically diffusing
certain Labradorite with copper. Care should be handled
with Labradorite, as it is sensitive to pressure and can easily crack or
Labradorite is used as cabochon
s and beads, mainly for necklaces and bracelets, but is also faceted for rings and cut into ornamental objects and spheres.
Treatments & Enhancements
Labradorite gemstones are natural and not treated or enhanced. A new gemstone form given the term Andesine
is laboratory-produced by subjecting Labradorite to diffusion treatment
The main sources of Labradorite are Canada (Labrador and Newfoundland), Finland, Ukraine, Madagascar, and Australia.
The color effect of Labardorite distinguishes it from all other gemstones.
