Color-change Smoky Quartz


This large, 48-pound Arkansas quartz cluster started life as a white crystal.
Some crystals like this, which contain traces of aluminum, will turn black when exposed to very high frequency light rays. This is called “irradiated quartz.”
The color change is permanent.
These perfect crystals are almost 300 million years old.
Enjoy their eternal beauty in the sunshine!
