18 Karat bi-metal turned edge cuffThis cuff is 1 3 4 inches wide. It is made of 18 K bi metal which is gold fused to silver. It is about 1000 times thicker than an average plated piece. I texture the bottom edges flip them over and you have a great contrasting color combination of blackened silver and gold. This will continue to look as it does for years to come, silver naturally turns black and gold remains gold.
