MSG1177: Deeply Tenebrescent Red Sodalite (Hackmanite) from Greenland

Description

Fluorescent Mineral Sales MinerShop
Deeply Tenebrescent Red Sodalite (Hackmanite)
Tunuliarfik, Ilimaussaq Complex, Greenland
2 3/4” x 1 1/2" x 1”, 1.4 oz
Brightly fluorescent both SW and LW. Most areas of green fluorescence is the typical uranyl activated mineral found on Ilimaussaq rocks.
The material from this locality is probably the winner in the color-change department. Brightly fluorescent both SW and LW - the natural color deepens to a light pink upon exposure to LW UV (or obscure sunlight) and to a deep purple (almost black) after exposure to SW. (Thus the nickname “Red Sodalite”.)
Upon exposure to SW UV the sodalite on this piece changes color to a deep purple - in seconds! Expose it to a bright white light (UV free halogen or LED spotlight held directly on the rock) and it reverts back to its natural color almost immediately.
The animation below shows the color change (tenebrescence) after exposure to longwave and shortwave UV.

A personal note from Mark Cole, MinerShop
"As many of my followers have noticed, I (Mark) have retired from active sales. My daughter, Valerie, has joined the MinerShop crew and will be taking over our sales. She has assumed my large inventory of Greenland and other world-wide minerals, has learned to take the same great photos you've come to expect, and will offer the same great service you've gotten used to. She grew up around these minerals and, thankfully, got the glow-bug herself at a young age. A father's dream to have one of his children appreciate our hobby, insuring a home for his lifetime's passion. Please support her in this transition, and be assured I'm behind her every step of the way."
