Gemstone Rings

Crafted in 18k white gold with a boulder opal center. Boulder opal is found in Australia where precious opal forms in veins and patches within brown ironstone boulders.Hardness ranges between 5.5 and 6 on the Mohs scale. Boulder opal is very durable due to the ironstone backing the opal forms on. Because water content within the opal is very low it almost never cracks or crazes as it ages.
