Ethiopian Opal was formed many million years ago but just recently discovered!

In the veins of Volcanic rock high up in the Ethiopian mountains you can find this rare but beautiful Gem.

The internal structure of precious opal makes it diffract light; depending on the conditions in which it formed it can take on many colors. Precious opal ranges from clear through white, gray, red, orange, yellow, green, blue, magenta, rose, pink, slate, olive, brown, and black. Of these hues, the reds against black are the most rare, whereas white and greens are the most common. It varies in optical density from opaque to semi-transparent.
