Where Product 1 holds a secret, this ring holds nothing back. The knife-edge cathedral solitaire is an architectural statement without hidden details, just a stunning square cushion cut diamond lifted high on steep cathedral shoulders above an open V-gallery wire basket, all the light of the room flooding into the stone from every angle. The knife-edge band, the same precision-sloped triangular profile, plays light against its sharp edges so the solid gold shank seems to vanish beneath the diamond. Clean. Confident. Unmissable. E color, VS1 clarity. Available in 1ct, 2ct, and 3ct, in solid 14K or 18K gold with IGI certification.
