Tenebrescence is the phenomenon that occurs when a mineral changes color after exposure to UV light. The color change is temporary, and can be reversed when the material is exposed to incandescent light. Tenebresence is the name given to a color change induced by UV light and when a deposit of colorless Scapolite from Afghanistan was tested with UV light, the result was remarkable. Colorless gems underwent a profound change of color to a saturated, medium blue. When the short-wave UV light was removed the stones immediately began to fade and returned to colorless within a few minutes. The stone is then ready to go through this cycle again and again.

the discovery of the new Scapolite was both a welcome treat to collectors and a boon for Scapolite itself. As the stone is a desirable rarity . The deposit did not produce a huge quantity of gem material.
