I've added a lot of photos! * Will be removed if not sold by 2025/12/31 * No price reductions This is an Australian black opal necklace purchased in Australia over 10 years ago. It displays beautiful play-of-color with red, green, and blue hues depending on the angle. The colors change quite a bit even with slight adjustments, so I've tried to take as many photos as possible. I bought it but didn't have many opportunities to wear it, so it's been sitting in my jewelry box. I hope someone will give it a good home. The setting is 18K white gold, with a hallmark. The side stones are 2 diamonds. The chain is included, but there is no hallmark and the material is unknown. To prevent fraud, returns and exchanges are not accepted after purchase. We do not accept returns for reasons such as a difference in image, so please check the images and content before purchasing. * When viewed from the side, a black layer can be seen, so it is believed to be a doublet opal. Please understand that this is not a solid opal before purchasing. [Material] 18K (hallmark present) [Stone] Black Opal / Side stones: Diamonds [Condition] Used a few times.
