Cushion Cut


Our Cushion Cut moissanite features a similar square silhouette to the Princess Cut but has rounded corners, making these stones more durable than diamond cuts with sharp edges.

Our signature stone, the Ethica Diamond, is not a lab grown diamond but a lab grown stone that is precisely cut from premium grade silicone carbide (moissanite) with a diamond infusion.

Each stone is grown under strict conditions, cut by hand and fully faceted to exact diamond proportions, giving each stone incredible depth and sparkle, and independently certified by the GRI.

Ethica Diamonds are as standard:

  • E colour
  • VVS1 clarity
  • Excellent cut

Please enquire if you would like different specifications.

Sometimes referred to as a Pillow Cut, Cushion Cut diamonds have an open culet (the bottom point of the stone) – the result is a deep, luxurious diamond with a romantic effect and dazzling sparkle; in fact, a Cushion Cut diamond is one of the most sparkly diamond cuts. The result is a deep, luxurious gemstone with a romantic effect.

Ever since the engagement of Prince Harry and Meghan Markle, we receive a lot of questions about the main stone in Meghan’s ring. It’s a stunning Cushion Cut diamond. This is is a square diamond shape with rounded corners and 61 facets. This cut reflects the light in a chunkier way than for example a Round Brilliant. This is what we call ‘the crushed ice effect’. The subtle crushed ice sparkle was very popular around the 1920s. That’s also why cushion-shaped diamonds can be fully appreciated in a vintage setting. The Cushion Cut was originally designed to be viewed by candlelight, and maintained enormous popularity for over 70 years during the Victorian period and is a modern interpretation of Princess. Even today, the vintage setting is the most beloved ring style for Cushion Cut diamonds. The development of this cut dates way back to almost 200 years old. The name, however, is quite modern. In the past, they called this shape the ‘mine cut’, a square diamond with rounded corners. The Cushion Cut is one of the most brilliant cuts of all square and rectangular shaped stones.
