RINGS MADE TO ORDER
Princess cut lab grown diamond engagement rings bring the clean geometric discipline of the square into the brilliance of the round brilliant cut. The princess cut is the most square-shaped brilliant-cut diamond: 90-degree corners, crisp edges, and the same faceting optimization as the round, in a format that makes a completely different visual statement at the same carat weight.
Every princess cut lab grown diamond engagement ring in the Ronora collection is made to order in our Surat studio. The center stones are Real CVD Lab-Grown Diamonds: VVS clarity, D-E-F Colorless range, grown using Chemical Vapor Deposition technology. The princess cut retains more weight from the rough than the round brilliant: a square outline wastes less of the octahedral diamond crystal, which means more diamond per carat spent.
The princess cut was developed in the 1980s as an answer to the question of whether a square diamond could achieve the same brilliance as a round one. The answer was largely yes, with the added benefit of a more contemporary architectural profile. The result is the second most globally purchased engagement ring shape after the round brilliant, prized for its modern geometry and its fire.
A princess cut lab grown diamond engagement ring suits those who prefer clean modern lines over the organic curves of the round or oval, and who want the security of brilliant-cut fire in a geometric format. Available in solitaire, halo, pave, and channel-set designs. IGI certification included for eligible selections. Made to order in 14K and 18K Solid Gold in White, Yellow, and Rose, plus 10K Gold, 925 Sterling Silver, and Platinum.
Ronora - Made for the Moments.
Sharp corners are the princess cut's signature and its weak point. Each one gets its own hand-set prong before the ring leaves our bench.
A contemporary shape backed by traditional assurance: IGI certification, free resizing, and returns on every ring.
The princess cut wastes the least rough diamond, and lab grown pricing multiplies that efficiency into visibly more carat for your budget.
It is the square shape with true brilliant-style sparkle, sharper and more architectural than a round but just as lively in light.
With proper setting, yes. We protect all four corners with dedicated prongs, which is where handmade setting earns its keep.
Pick princess for crisp square edges and geometric sparkle, radiant for softer corners and a crushed-ice look. Both photograph beautifully.
Face up it measures slightly smaller than a round of equal carat, but its corner-to-corner spread and sharp flash compensate on the hand.
Solitaire and channel settings keep it modern, halos square it up into serious presence. All made to order.
Yes, every eligible princess center stone ships with its IGI certificate.
