This is a very sweet little carved opal. It is only small, .80ct, 9x5mm. But it would make the nicest ring. It has an N4 body tone, which means it has a very dark natural back. As you move the opal, large chunks of colour appear, Green, Red, Orange and more. The opal can be a bit directional, but in a ring and with your hand movements, the colours would certainly have the wow factor.
