Light Sensitive Minerals



There is a great article in the November 2008 Rock & Gem Magazine, "Light-Sensitive Minerals: Why Some Specimens Lose Their Color" by Bob Jones. He discusses the chemical make up that creates the light sensitivity and how to care for and display light sensitive minerals. Some of the minerals he lists are:
Brown Zircon
Aragonite
Halite
Celestine (Blue)
Yellow Sapphire
Green Spodumene
Colored Diamonds
Smoky, Rose, Amethyst Quartz
Pink, Yellow, and Blue Fluorite
Red Spinel
Maxixe Emerald
Brown, Sherry, and Blue Topaz
And there are more.

It's very well done article, check it out if you haven't yet!
