This Roberto Coin Cento Diamond Tennis Bracelet is 18k 2.4tw in diamonds. The Cento diamond is unique in that it has 100 facets. The color is F, and the clarity is VVS2. The bracelet was purchased from Bloomingdale's. The third photograph shows the Roberto Coin signature ruby. The bracelet was sent to Roberto Coin. It looks new. Everything was checked, tightened, polished, and rhodium plated. This is a beautiful bracelet that I have always received compliments on.
