Product Description

Beautiful green flash rolls across the face of this solid Australian pipe opal.  It was found on our mining lease in western Queensland.  This pipe opal has some natural adhering sandstone still on the back.  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.  (Not a doublet)

Opal size: 10.5mm long x 7.2mm wide

Ring size: US 9 1/4   or   GB S 1/2
