The cathedral solitaire is architecture in miniature. Twin cathedral arches rise from the shank to elevate the center stone, lifting the oval brilliant cut diamond high above the hand where it catches light from every direction. The tapered, high-polish shank disappears beneath the stone, ensuring the diamond is always the focal point. This is not a ring that competes for attention. it directs it entirely to your oval lab grown diamond. Available in 1ct, 2ct, and 3ct center weights, handcrafted in solid 14K or 18K gold, and certified by the IGI.
