Fluorescent minerals are one of nature’s marvels. What look like normal rocks in daylight burst into life when viewed under ultraviolet light.

A display of Fluorescent Minerals in a private collection.

Not all minerals react to fluorescent light but the ones that do can be spectacular. Some minerals react under long wave UV, some under Mid wave UV, but the most spectacular are the ones that react to short wave UV.

 

Collectors may build their collection by wavelength or by location, or both! Some of the most famous and desirable locations for collectors are the Franklin/ Sterling Hill mines in New Jersey, USA, the Ilimaussaq Complex in Greenland, and the Puttapa deposits in Australia.
