A 0.5 carat lab-grown diamond center is a size that sits comfortably on the hand for everyday wear. A round one measures about 5 mm across. Elongated shapes such as oval, pear and marquise spread the same weight over a longer outline, so they can look a little larger on the finger. The half carat figure is the center alone, so rings with pavé or side accents carry a bit more lab-grown diamond in total.
Every ring here comes in 10K, 14K or 18K gold. 10K holds the least gold and stands up best to knocks. 14K balances color and strength and is the most popular choice for a 1/2 carat lab-grown diamond ring in 14K gold. 18K has the richest color and is a little softer, so it shows scratches sooner. Yellow and rose gold bring warmth to a white center, while white gold gives a cool, bright look.
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.
They start from about $750 for the finished ring, and that price already includes the half carat lab-grown diamond center. Most rings in this collection sit between about $1,000 and $1,100 in their lowest-priced metal option. Higher karats and styles with pavé, halos or side accents cost more. Lab-grown diamonds cost far less than natural diamonds of the same size, which keeps a finished gold ring in this range.
