Sophia Lab-Grown Diamond Engagement Ring in 14K White Gold (IGI Certified)
The Sophia cushion diamond engagement ring is built around its band: a shimmering strand of pavé lab diamonds entwined with a lustrous ribbon of precious metal, carrying an IGI-certified lab-grown cushion diamond — D color, VVS clarity, ~2ct at 7×7mm — in solid white gold. Sparkle and polished metal braided into one continuous line beneath a pillow-soft center. Choose your karat and metal below.
The twist band
Where most bands choose either pavé or polished metal, the Sophia braids both: one strand fully set with pavé lab diamonds, the other a clean, lustrous ribbon of gold, twisting together toward the cushion center. The interplay reads as two lives intertwined — and gives the ring sparkle plus a bright metallic gleam from every angle, on a comfortable 2.3mm band. A matching wedding band can be custom made to order — message us. Explore more lab-grown diamond engagement rings and gemstone engagement rings.
The diamond
The cushion cut center is a genuine lab-grown diamond — chemically, physically, and optically identical to a mined diamond (same carbon structure, same 10 Mohs hardness, same brilliance), grown in a lab and clearly disclosed. It's D color (the top, completely colorless grade) and VVS clarity, and every ring ships with an IGI certificate and unique serial number. Learn more in our complete guide to lab-grown diamonds, how lab-grown diamonds are made, and IGI vs GIA certification.
Choose your metal & karat
Every version is solid white metal throughout — never plated or filled. Pick the karat that fits your priorities using the Metal selector; each is priced accordingly. Not sure which to choose? Our 10K vs 14K vs 18K gold karat comparison guide breaks down the trade-offs.
10K White Gold
41.7% gold. The most budget-friendly and hardest-wearing option — a great everyday choice.
14K White Gold
58.5% gold. The most popular bridal choice — the sweet spot of durability, warmth, and value.
18K White Gold
75% gold. A richer, more luxurious feel with the highest gold content of the golds.
Platinum
Naturally white, exceptionally dense, and hypoallergenic — the premium heirloom metal, never needs re-plating.
Why solid white metal
Every option here is solid — the metal itself, not plating or vermeil over a base metal. The polished ribbon strand shows the metal off as a design element, and the cool white lets the D-color diamond blaze. The color is permanent: it won't wear off and won't turn your skin green. White gold in 10K, 14K, or 18K takes a rhodium finish for a bright mirror-white; platinum is naturally white and develops a soft patina over time. Yellow or rose gold is also available on request.

Cushion cut lab diamond engagement ring FAQs
Is the diamond real?
Yes — a genuine lab-grown diamond, chemically and optically identical to a mined diamond, with the same 10 Mohs hardness and brilliance. Real diamond with a lab origin, clearly disclosed — not moissanite or CZ.
What makes the band special?
It's a twist design: a pavé diamond strand braided with a polished gold ribbon — sparkle and gleam interwoven beneath the cushion center.
What's the difference between 10K, 14K, 18K, and platinum?
The karat number is how much of the metal is pure gold: 10K is 41.7%, 14K is 58.5%, and 18K is 75%. Lower karats are harder and more affordable; higher karats feel more luxurious. Platinum is a naturally white precious metal — denser, hypoallergenic, and never needs re-plating. All are solid throughout. See our karat comparison guide for details.
What do D color, VVS, and IGI certified mean?
D is the highest color grade — completely colorless. VVS means inclusions are virtually invisible under 10× magnification. IGI is one of the leading diamond grading labs; your certificate documents the stone's exact weight and grades with a unique serial number.
Is there a matching wedding band?
Yes — a matching band can be custom made to order. Message us and we'll design it to nest with the twist band.
Is this real solid white gold?
Yes. Every white-gold option is solid 10K, 14K, or 18K throughout — the metal itself, not plating or vermeil. The color is permanent, won't wear off, and won't turn skin green. A platinum option is also available.
