Jewelry Hints, Tips and Tricks: Preventing Light Damage To Your Gemstones

Prevent Light Damage To Your Gemstones!

While not all gemstones fade if subjected to the sun's rays there are those that will fade, even from artificial lighting and dyed stones can always fade when exposed to light sources.

Un-dyed gemstones can also fade. This is usually due to less stable atoms than those found in stones that do not fade as readily or even the loss of water from a stone. Irradiated stones will also fade more readily than those that are natural so when selecting gemstones keep this in mind. 

Never leave these gemstones in sunlight or bright artificial lighting:
