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 .

Opal is a birthstone for Libra , Taurus  and the months of October, September and November...

Opals are said to encourage stable relationships and companionship.
