Aslam Bakshi, owner of Diamond Images U.S.A., says “The ring is a traditional Tiffany style ring with a pear shape diamond in the center along with two tapered diamond baguettes on each side. The center diamond should be at least 4-5 carats… with an approximate retail value of between $250K and $300K.”
