There is a reason the six-prong cathedral solitaire has endured for over a century. Six rounded prongs hold the round brilliant center stone in a commanding coronet basket, lifting it high on cathedral shoulders where it receives light from every direction and returns it as pure fire. The sleek, high-polish band tapers away from the setting to keep the focus entirely on the diamond. No distractions. No compromises. Just the stone and the light. Available in 1ct, 2ct, and 3ct, crafted in solid 14K or 18K gold with IGI certification on every diamond.
