About Labradorite :-
The Gemstone 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. Labradorite is named after the Canadian province of Labrador, the classic locality of this gemstone. Labradorite is often heavily flawed 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. 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.
