This Opal has orange glints in a mainly sparkling blue matrix, with a hint of green .
Opals are created from silion dioxide solutions, which entered cracks in ancient rocks during the Cretaceous geological period. Once the water evaporated , the tiny spherical silica particles eventually created Opals. White light is refracted by these spheres and is broken up to form the colours of the spectrum .
