Pretty green solid Australian pipe boulder opal set in 18k solid yellow gold. It is bezel set with a 0.023ct diamond and swinging bail. The opal is almost solid crystal with a very small amount of the host sandstone still adhered to the back of the opal.
Pipe opal occurs when fragments of tree roots or any organic material are trapped in sediments on an opal level and in time some of resulting cavities are replaced by potch or precious opal. The sandstone has been stabilised with a polymer resin to increase strength and durability and avoid chipping during setting process. (Not a doublet)
