Product Description
This IGI certified cushion cut engagement ring is built around a clean solitaire layout that keeps full attention on the center diamond. The cushion cut lab grown diamond features soft corners with a square outline, giving the ring a balanced shape that sits naturally on the finger. Held in a classic four prong setting, the stone remains open from the sides so more light can pass through the diamond. The slim plain band keeps the profile minimal, making the center stone appear more prominent without extra detailing around it.
Available from 0.25 CT to 5.00 CT, this design works equally well for someone wanting a small everyday solitaire or a larger statement cushion cut ring. The band measures approximately 1.80 mm wide with a 1.70 mm depth, giving the ring a lightweight feel while still maintaining structure for daily wear. The low basket style setting keeps the diamond stable and wearable, while the smooth inner band provides a comfortable fit across different finger sizes.
Each lab grown diamond is offered in D/E/F color with VVS1, VVS2, VS1, or VS2 clarity options and graded in Excellent or Very Good cut. The ring is available in 925 silver, 935 Argentium silver, 10KT, 14KT, or 18KT solid gold, as well as 950 platinum in white, yellow, or rose tone finishes. IGI certified options are available for 1.00 CT and above. Every piece includes the Ouros Authentic Jewelry Certificate and can be customized for ring size, metal type, diamond size, and engraving.
