Round Solitaire Lab-Grown Engagement Ring — Platinum

From $2,300Starts at 1.50ct Round · D–F · VVS2 · IGI
A round brilliant lab-grown diamond set in a clean four-prong solitaire on an 18K platinum 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: Solitaire Metal: Platinum (also available in 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 Round brilliant returns more light than any other cut — 58 facets engineered for maximum scintillation. A 1.8mm slim band keeps the stone as the visual centerpiece and prevents the metal from competing. 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 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+. 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. Can I customize the metal or carat? Yes. Choose 14K or 18K white, yellow, or rose gold. Center stone ranges from 1ct to 5ct.
