A radiant cut pairs the straight sides and clipped corners of an emerald cut with brilliant-style faceting, so it gives the outline of a step cut with far more sparkle. The trimmed corners also make the stone less likely to chip than a sharp-cornered square. At 6 carats the center reads clearly from across a room. Lab-grown diamonds share the chemistry, hardness and fire of mined diamonds, so a stone this size holds up to daily wear.
A vintage-inspired style with filigree detail is also available.
Gold comes in 10K, 14K or 18K in white, yellow or rose; platinum is naturally white and dense. White metals keep the center looking crisp, while yellow and rose gold warm it. Bands run from about 1.8 to 2.8 mm wide, and every style offers 2.2 mm. Rings start from about $4,500 with the center included, and most cost between about $4,900 and $5,100.
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.
At Renaissance Jewel, from about $4,500, and most rings here cost between about $4,900 and $5,100. That price covers the finished ring with its 6 carat radiant lab-grown diamond center set, in the lowest-priced metal; other metals and gold karats cost more. Lab-grown diamonds cost far less than natural diamonds of the same size, which keeps a center this large within reach.
