At 8 carats a radiant cut covers much of the finger, and its brilliant facets throw sparkle while the straight sides keep the look tailored. The cropped corners make it more chip-resistant than a sharp-cornered square, which is reassuring on a stone this large. Lab-grown diamonds rank 10 on the Mohs scale, the same as mined diamonds, so the center is built for everyday wear.
Gold comes in 10K, 14K or 18K in white, yellow or rose; platinum is dense and naturally white, and it holds prongs firmly around a large center. Bands run from about 1.8 to 2.8 mm, and every style offers a 2.2 mm band. Rings start from about $13,700 with the center included, and most cost between about $14,000 and $14,300.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
