A round brilliant lab-grown diamond set in a clean four-prong solitaire on an 18K gold band. The most-asked-for engagement ring format in the US, engineered to the standards of a modern atelier. Specifications Center stone: Round brilliant lab-grown diamond, IGI certified Color & clarity: D–F / VVS2 Cut grade: GIA Excellent equivalent Setting: Four-prong solitaire on cathedral shoulders Metal: 18K Yellow, White, or Rose Gold, hand-finished Band width: 1.8mm Inner diameter (US size 6.5): 16.9mm Certification: IGI Why this design The round brilliant returns more light than any other cut. A solitaire setting keeps the band slim and removes all visual competition from the stone — which is why this combination has been the default for over a century. We pair it with a 1.8mm band so the stone reads as the entire ring. Made to order Each ring is hand-finished to order. Production and shipping take 12–16 business days. Includes IGI certificate, complimentary resizing within 60 days, and lifetime cleaning. Frequently asked Is this a real diamond? Yes. Lab-grown diamonds are chemically and optically identical to mined diamonds — same carbon structure, same 10 Mohs hardness, same fire. The only difference is origin. What size diamond should I choose? The most chosen size at Sula is 2ct, which reads as substantial on most ring sizes without overwhelming the hand. For a quieter look try 1.5ct; for a statement, 3ct+. Can I customize the metal or carat? Yes. Choose 14K or 18K white, yellow, or rose gold. Center stone ranges from 1ct to 5ct.
