How Much is a Cabochon Black Opal?
- What is a cabochon Opal?1 Answer1stDibs ExpertAugust 17, 2021A cabochon opal is an opal that’s cut in a dome shape. There are two types of opal: common and precious. The former is, as its name implies, not very rare. Precious opal, on the other hand, is more rare than diamonds and considered very high quality.
- 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.
