Hackmanite 0.040ct loose

Rare stone, hackmanite. It has a strange feature: when you expose it to a black light for about 5 to 10 seconds, the color changes to a pale purple, and it does not return to its original color for a while. This is a relatively new type of rare stone that was discovered on the Kola Peninsula in Russia in the 1980s. Since the hardness is low, you need to be careful not to hit it against hard objects. It is a loose type of hackmanite with particularly high transparency.
