Buying guide
The karat sets how much pure gold the ring holds. 18K is richest in color and a little softer. 14K balances color and toughness and is the most common choice for a 4 carat gold engagement ring. 10K is the hardest and the most budget-friendly. White gold is plated with rhodium for its bright finish; yellow and rose gold keep their color on their own.
A 4 carat round lab-grown diamond is roughly 10 mm across. Oval, pear, marquise and emerald shapes spread the same weight along the finger and look longer. Cushion and radiant are softer squares with lots of sparkle. Princess and Asscher are crisp squares, and heart is the boldest choice at this size.
A big center needs a band that can support it. Solitaires on a plain or rounded band keep things simple. Pavé bands add small lab-grown diamond accents along the shank. A halo frames the center and a hidden halo sits beneath it. The three stone ring and the rings with pear or marquise side accents give a wider, fuller 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.
Lab-grown diamond rings in this collection start from about $2,400 with the 4 carat lab-grown diamond center set, in the lowest gold option, and most sit between about $2,700 and $2,850. Higher karats and fuller styles cost more. As for worth after purchase, lab-grown diamonds have little resale value, so treat the ring as something to wear rather than an investment. The gold itself keeps its metal value.
