Tugtupite Tumbled 16. 4 grams
This Tugtupite tumbled stone displays fluorescent pink and orange colors under short and long wave UV light. Interestingly enough, the UV light also strengthens the pink coloring when the light is taken away. We have posted pictures of the stone when it has not been exposed to UV light for months, and then posted one picture with a ruler days after it was exposed. There is an increase intensity of the pink color that seems to last for weeks on end. Location: Greenland. Dimensions: 1.01" x 0.81" x 0.80". Weight: 16.4 grams. 15F499.
