The radiant cut diamond is one of the most versatile and technically accomplished shapes in modern gemology. Created in 1977, the radiant cut combines the elegant rectangular outline of an emerald cut with the brilliant-cut faceting pattern of a round diamond, the result is a shape that offers the refined geometry of a step cut with the fire and sparkle of a brilliant. No other diamond shape gives you both in equal measure.

At Trusamra, every radiant cut lab grown diamond engagement ring is handcrafted in solid 14K or 18K gold. white, yellow, or rose, and certified by the IGI (International Gemological Institute). Our lab grown radiant diamonds are chemically, optically, and physically identical to earth-mined diamonds. The only difference is origin: grown sustainably in a controlled environment, free of mining, conflict, and environmental destruction.

One of the radiant cut's most distinctive qualities is its cropped corners, a practical design choice that makes the diamond more durable and less prone to chipping during daily wear compared to princess or emerald cuts with sharp corners. The radiant's elongated shape also creates a flattering, lengthening effect on the finger, making it appear larger per carat than many other shapes.

Our radiant collection offers the cathedral solitaire, an architectural setting that lifts the radiant cut diamond high on cathedral shoulders for maximum light exposure and dramatic presence. Whether you choose 1ct, 2ct, or 3ct, every diamond comes with a physical IGI grading report, and every order ships free, fully insured, across the United States.
