Fluorite with Chalcopyrite & Radiation Induced Spots

Purple-blue Fluorites containing numerous, prominent dark spots. These occur due to local, tiny ingrown bits of radioactive material that excites the electrons of some fluorite molecules around them and causes a permanent “smoky” effect as happens also in smoky quartz. It is very rare to see this dispersed pinpoint phenomenon in fluorite!
