Buying guide
The plainest versions sit on a thin or rounded band, so nothing competes with the center. A pavé band adds small lab-grown diamond accents along the shank. A hidden halo places a row of accents under the center that shows only from the side. A cathedral setting lifts the center on arched shoulders over a graduated pavé band.
A 4 carat round lab-grown diamond is roughly 10 mm across, a large stone on any hand. Oval, pear, marquise and emerald shapes stretch that weight along the finger and look longer. Cushion and radiant are softer squares with strong sparkle, and princess and Asscher are crisp squares. Heart is the most unusual choice and reads clearly at this size.
Platinum is dense and very durable, and it keeps a white look without plating, which makes it a strong choice for a 4 carat lab-grown diamond solitaire engagement ring. White gold gives a similar look at a lower price. Yellow and rose gold add warmth. Higher karats have more gold and a richer color, while 10K is the hardest.
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.
Usually from about $2,550 for the finished ring with its 4 carat lab-grown diamond center set, in the lowest gold option. Most 4 carat solitaire rings here sit between about $2,850 and $2,900. Platinum and 18K gold cost more. Lab-grown diamonds cost far less than natural diamonds of the same size.
