  • Rbc (round Brilliant Cut) Diamond - An RBC diamond is a "Round Brilliant Cut diamond." It is a popular diamond cut, known for its excellent light performance and overall brilliance. A round brilliant cut diamond has 58 facets, which are precisely cut and polished to maximize the diamond's brightness, fire, and scintillation. The RBC cut is the most popular diamond shape, accounting for approximately 75% of all diamonds sold worldwide.
  • Doublet and Triplet - A doublet and a triplet are both composite imitation stones, consisting of two or three joined layers. A triplet is made with the crown and base of genuine material, but with a centre layer, usually of glass, the object being to make the stone appear larger than it really is. A doublet consists of only two layers.

    Opal doublets are quite common and consist of a thin layer of opal cemented to an opal matrix or black glass.
