1. Round Brilliant Cut

2. Princess Cut

  The Princess Cut diamond emerged in the 1960s as a modern diamond cut. It is characterized by its square or rectangular shape, typically with 57 or 58 facets.

  The Princess Cut is renowned for its high brightness and fire, and because the cut retains more of the rough diamond, it offers better value for money.

  Radiant Cut diamonds have slightly rounded corners and more facets, making them easily distinguishable from Cushion and Emerald Cuts.

5. Emerald Cut

6. Asscher Cut

  The Asscher Cut lab diamond was invented by the Asscher brothers in the Netherlands in 1902, and it exudes a distinct vintage charm.
