Pastel colours are seen in this solid pipe boulder opal from our mine in western Queensland. It is bezel (rubover) set in solid sterling silver with four cubic zirconias on either side and rhodium plated to prevent tarnishing.
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 cavaties 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.
