Fluorescent Sodalite - Greenland
$55.00 USD
SKU: MSG1569B
Shipping and Delivery
Fluorescent sodalite from Greenland with some pieces exhibiting tenebrescence, where the stone’s color changes to a purple when exposed to UV light. Sodalite that is tenebrescent is also known as hackmanite.
Note: Tenebrescence is usually displayed when exposed to shortwave (254nm) UV light. If there is tenebrescence from longwave (365nm) UV light, these pieces are considered higher value as they are rarer.
Known in the fluorescent mineral hobby as the brightest sodalite in the world, Greenland Sodalite has become the benchmark in the UV mineral world, setting a world-class standard to which all other sodalites are compared.
Fluorescent sodalite, or hackmanite from Greenland is a rare find for collectors. You won’t find much of this material on the market. Each piece is uniquely amazing.
"Red" Sodalite (Hackmanite) - Deeply Tenebrescent Greenland Mineral
Red sodalite is named for the color it takes on when exposed to sunlight; it is nicely tenebrescent under longwave UV. Under shortwave UV the color deepens, in seconds, to almost black in some areas.
