Buying guide
The range runs from clean solitaires on a plain or pavé band to busier looks: a cathedral setting with a graduated pavé band, hidden halo and halo styles, a vintage look with filigree, three-stone rings, and rings with pear or marquise side accents. A 3 carat lab-grown diamond center is the main event in every one. Accents set in the band or halo are lab-grown diamonds too, and they add to the ring's total.
Yellow gold gives the classic warm look and makes a white center stand out by contrast. White gold reads bright and cool, close to the color of the stone. Rose gold has a soft pink tone that suits vintage and halo styles. As a 3 carat gold engagement ring, 14K is the usual choice: it balances color and strength. 18K has a richer color and is a little softer, and 10K is the hardest and lowest in price.
Prices start from about $1,950 for the finished ring with its lab-grown diamond center, and most sit between about $2,250 and $2,400 in the lowest metal option. The style, shape and karat you pick move the price up from there. Lab-grown diamonds cost far less than natural diamonds of the same size, which is what keeps a 3 carat center within reach.
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.
In this collection, a 3 carat gold ring with a lab-grown diamond center starts from about $1,950, and most cost between about $2,250 and $2,400 before you choose a higher karat. As for worth after purchase, lab-grown diamonds have little resale value, so treat the ring as something to wear, not an investment. The gold itself keeps its metal value.
