Loving Labradorite!

December 13, 2010 Leave a comment

Recently I’ve started using Labradorite in my jewelry, and I’ve fallen madly in love! The shimmering greens and blues are like no other stone, and it has a naturally luxe quality.  It is a mineral whose charm is not fully noticed and may be overlooked if not viewed from the proper position. It might be seen generally as a dull, dark looking mineral, until the colorful shiller is observed glowing on the surface. Labradorite can produce a colorful play of light across cleavage planes and in sliced sections called labradorescence. The usually intense colors range from the typical blues and violets through greens, yellows and oranges. Some rare specimens display all these colors simultaneously.

The color display is from lamellar intergrowths inside the crystal. These intergrowths result from compatible chemistries at high temperatures becoming incompatible at lower temperatures and thus a separating and layering of these two phases. The resulting color effect is caused by a ray of light entering a layer and being refracted back and forth by deeper layers. This refracted ray is slowed by the extra travel through the layers and mixes with other rays to produce a light ray coming out that has a different wavelength than when it went in.
