Questions About Boulder Black Opal
- 1stDibs ExpertAugust 17, 2021An Australian boulder opal is an opal mined from a large ironstone boulder under the ground. This type of opal is the second most valuable opal behind the black opal. Spot an Australian boulder opal by checking for a solid layer of brown ironstone left on the back of the stone. Shop Australian boulder opals on 1stDibs.
- 1stDibs ExpertApril 5, 2022To see if your black opal is real, check the potch on the back. Double-sided opals are rare, so if there is a lack of potch and color all the way through, this could indicate a fake. Shop a collection of expertly vetted opals from some of the world’s top sellers on 1stDibs.
- 1stDibs ExpertOctober 12, 2021Black fire opal can vary in worth, from $10 per carat to $10,000 per carat. Black opals are generally considered extremely valuable because of their vibrant spectrum of colors and are one of the most enchanting stones in the world. On 1stDibs, shop a range of vintage black fire opal jewelry.
