Buying guide
Round is the brightest shape and the most classic. Oval, pear and marquise are longer, so a 4 carat center looks larger on the finger and makes the hand look slimmer. Cushion has rounded corners and broad flashes of light; princess and radiant are square or rectangular with lively sparkle. Emerald and Asscher are step cuts with a calm, mirror-like look. Heart is the most romantic and reads best at a larger size like 4 carats.
The halo of small lab-grown diamonds follows the center's outline and adds a bright frame around it. Filigree, the fine openwork in the metal, gives this 4 carat halo engagement ring its vintage character. Three rows of pave lab-grown diamonds run along the band, which comes in widths of 2 mm or 2.2 mm. These accents come in addition to the 4 carat center stone.
Platinum is naturally white, dense and hard-wearing, and it costs more than gold. Gold comes in 10K, 14K or 18K white, yellow or rose gold. Prices start from about $4,400 in the lowest-priced metal, with the 4 carat lab-grown diamond center included.

Rings on this page start from about $4,400 in the lowest-priced metal, and that includes the 4 carat lab-grown diamond center already set. Platinum and 18K gold cost more than 10K or 14K gold, so the metal you choose sets the final price. Lab-grown diamonds cost far less than natural diamonds of the same size.
