3 Carat Cushion Cut Lab-Grown Diamond Engagement Ring in 14K White Gold (IGI Certified)
This 3 carat cushion cut diamond ring centers an IGI-certified lab-grown cushion diamond — D color, VVS clarity, ~3ct at 8×8mm — above a shimmering strand of pavé lab diamonds entwined with a ribbon of white gold, in solid 14K white gold. Pillow-soft facets at full statement scale: the biggest diamond in our cushion family.
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. At ~3 carats, the cushion's rounded-square facets throw broad, soft flashes of light. Our moissanite vs lab-grown diamond guide and lab-grown diamond explainer cover how it compares.
The entwined pavé setting
A strand of pavé lab diamonds twists with a polished ribbon of white gold beneath the cushion center — two lines interwoven, sparkle and metal in a continuous braid. A matching wedding band can be custom made to order — message us. Explore more lab-grown diamond engagement rings and solitaire engagement rings.
Why solid white gold
This ring is solid 14K white gold — the metal itself, not plating or vermeil over a base metal. The cool white lets the three-carat D-color diamond read at maximum brilliance. The color is permanent: it won't wear off and won't turn your skin green. Also available in yellow or rose gold on request, or upgraded to 18K.

3 carat cushion cut diamond 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.
How big does a 3 carat cushion look?
About 8×8mm — a true statement stone. The cushion's rounded-square outline wears broad on the finger, and the slim 1.7mm band makes it read even larger.
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 this ring.
Is this real solid white gold?
Yes. The ring is solid 14K white gold throughout — the metal itself, not plating or vermeil. The color is permanent, won't wear off, and won't turn skin green.
