Gorgeous cut Australian Opal necklace for sale! This color came out of Lightning Ridge, Australia. The color comes from solid black Opal, but was too thin to make its own stone. Attached as backing is its brothers black potch base. This is the real deal! I cut all of my opals from a rough state, shape, polish, and mount them myself! This stone is beautiful with flashes of purple! Overall, the cut is very eye-clean. Measuring 2.13 carat weight and 8X10 mm. Chain is an 18 inch stainless steel snake chain. Bezel is 925 sterling silver. Comes in a little gift box!
