Round Lab Grown Diamond
Engagement Rings


The round brilliant cut is the most popular diamond shape in the world, and it has been for over a century, engineered with precise mathematical symmetry to return the maximum possible light to the eye.

Its 58 facets produce a fire and brilliance that no other shape can match. When you pair a round brilliant cut with a lab grown diamond, you get all of that performance, ethically, sustainably, and without compromise.

At Trusamra, every round 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 diamonds are chemically, optically, and physically identical to earth-mined diamonds. The only difference is origin: grown in a controlled environment, free of mining, conflict, and environmental destruction.

Our round cut collection spans every major engagement ring style, from the iconic six-prong solitaire to halo designs, three-stone trilogy rings, and tapered baguette settings. Made to order in 1ct, 2ct, and 3ct with a physical IGI grading report and free, fully insured US shipping.
