Boulder Opal Cut Stone – Green "Grassy" Pattern, Western QLD

An Australian Boulder Opal solid cut stone from Western Queensland with strong green colour play and an unusual "grassy" linear pattern — the kind of painted-landscape effect that makes boulder opal a favourite among collectors. Subtle blue tints shift through the stone as it catches light.

Sold as a loose stone, ready to be set or kept unmounted as a collector's piece.

About Boulder Opal

Boulder opal is found only in Western Queensland, Australia, where seams of precious opal form within ironstone boulders. Unlike other opal varieties, boulder opal is cut with its natural ironstone host rock left on the back of the stone. This dark backing intensifies the colour play and produces the "picture stone" effect — unrepeatable painted-landscape patterns that make each boulder opal one of a kind.
