"The hues of the opal, the light of the diamond, are not to be seen if the eye is too near. "
Opal is formed from the process of rain seeping down into crevasses in rocks, leaving behind silica that hardens into the stone.
Opal is one of the few gemstones that has been found outside of planet Earth, specifically on Mars!
The valuable opal color combinations is red and blue on the stone together, this is also the rarest.
Opals contain more colors than any other gemstone in the world.
One of the most unique aspects of opals is the way in which they shimmer in light and radiate a number of dazzling colours due to the tiny silica fragments throughout the stone.
