Gemstone of the Week: Labradorite

("Liadan" by Handmaden Designs)

Labradorite is a beautiful gemstone from the Feldspar group.  The gemstone was first found in Labrador and this name is generally used to refer to a dark, opaque feldspar with flashes of colour when viewed at the correct angles.  This effect is known as labradorescence and the colours it produces are bright blue, green, yellow, orange, and sometimes (though rarely) purple.  

There are a few examples of stones referred to as labradorite that are more transparent in colour. These stones include, Oregon Sunstone, Spectrolite, and Rainbow Labradorite (often sold as Rainbow Moonstone). 

Labradorite can range in value from $10-$100 per carat. Oregon Sunstone, however, is much more valuable and can be as much as $2,500 per carat.
