Emerald Radiant Cut


Emerald Radiant Cut diamond rings are brilliantly sparkly and often described as the best of both worlds. This cut is perfect for those who are seeking the breathtaking combination of the rectangular shape with the sparkle of a Round Brilliant cut diamond.

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.

Our Emerald Radiant moissanite is diamond infused and GRI certified, making it a perfectly fine alternative to diamond. A relatively new diamond shape, the Emerald Radiant cut was designed by Henry Grossbard in the late 1970s. He created a cutting technique that combined the best elements of Emerald and Round diamond shapes–allowing Emerald Radiant diamonds to exhibit incredible brilliance and fire. The Radiant is also the first cut to have a brilliant-facet pattern applied to both the crown & pavilion which makes it exhibit fierce shine with much more brilliance and sparkle.

Its quadrilateral form and 70 brilliant facets also make it similar to the Princess design, but its rectangular shape and blocked corners again emulate the Emerald figure. It is stunningly dramatic as a solitaire, but also compliments arrangements with side stones such as Baguettes, Trillions, or Pears.

The Emerald Radiant moissianite stones shown on the model’s hand are for reference only. Actual carat weight availability may vary.

In the event that another jeweller sets your stone, the Lifetime Stone Guarantee will be void.
