This 4.70ct natural boulder opal from Queensland formed within its ironstone host rock, and has been cut as a freeform cabochon that keeps the stone's natural character.
Flashes of red and orange glow across the warm brown ironstone, joined by sparks of green, blue and violet that shift and move with the light, so no two angles look the same.
Untreated and certified by our in-house FGAA gemmologist, with the certificate included. The ironstone backing gives the stone added strength, making it a distinctive choice for a pendant, or for a ring in a protective bezel setting. With a hardness of 5.5 to 6.5 on the Mohs scale, it is best suited to pieces that are not exposed to hard knocks.
