Large 40mm 22.32ct Australian Boulder Opal


This absoultally stunning boulder opal is what you would call a "Nightstone" as even in low light the piece still has beautiful green and violet fire. It was formed in an opalized wood deposit in Winton, Australia, where old branches and debris have been replaced by opal forming beautifully elegant opal specimens.

The piece was cut in house at our Brisbane Arcade store.
