Product Details

Our rainbow trillions have a transparent base and multicolored fire. They are cut in a traditional trillion shape. Rainbow opals, these have a clear transparent base and flash the colors of the rainbow with brilliant red, yellow, blue, and green fire. Because of its transparency, the outline of the stone disappears in clear glass (which is why some people call them "ghost opals") and flashes only the rainbow of opal fire in the middle of the glass. Rainbow opals create a cool effect when you want to put the fire in the glass with less emphasis on the shape of the opal.These faceted squares are stunning. Gilson opal is a lab-created opal that's chemically similar to natural opal . (THESE CAN BE ENCASED IN GLASS){{{ENCASEMENT INCLUDED}}}
