AUSTRALIAN MADE
This is a natural, cut, and polished Matrix Boulder Opal from Queensland.
The cabochon is a freeform oval shape with fine, intricate patternation containing multi-colour flashes of bright red, orange, yellow, green, blue and purple opal.
Approximate dimensions are 26x16mm, carat size 21ct.
Only found in Western Queensland, Boulder Opal formed millions of years ago in seams within ironstone or sandstone boulders where silica rich water seeped down into cracks and crevices and over time formed opal. Only a rare few will exhibit the amazing patterns and vibrant colours associated with this type of opal.
Photographs have been taken when wet, in various lighting conditions and have not been enhanced in any way.
