This is a beautiful Mexican opal that has a property known as ‘Contraluz’. When light is directed above the Opal there is very little play of color like other Opals. However, when the light is behind the Opal, the color is incredible. This is the exact meaning of Contraluz.
One of the photos I have taken is with the light above the Opal.
These Opals are considered rare and hard to find. This is truly a unique Opal
