The item is a opal and diamond pendant. There are three round diamonds, prong set above the opal. These stones are held in with three prongs each. The total carat weight of the diamonds is .03. The opal is held in with four prongs and measures 5x3 millimeters. There is a lot of color in the opal. The pendant and chain are 14k white gold. The chain is a rope chain with the small spring ring catch. If you want a picture of the catch let me know. The chain is 1 millimeter wide and 18 inches long or 45.72 centimeters. The item weighs 1.2 grams. I will provide a nice pendant box.
