This vintage custom made bracelet is circa 1960's. The metal is 18k yellow gold and the gemstones are diamonds and mosaic opal doublets. This bracelet weighs 49.3 grams. There are 44 diamonds in and around the mosaic tables and they average about 1.45mm each for a total weight of .66 ct. The diamonds are H-I in color and VS in clarity. The bracelet measures 1 1/4 inches at it's widest and 1/4 inch at the back at it's most narrow point. It is slightly oval in shape and the wrist opening measures 1 3/4 inches by 2 1/4 inches. I have a 6 1/2 inch wrist and it fits me fine and doesn't "roll". It is in great condition and there is a safety chain attached near the side clasp. This is a hinged style bangle.
