Buying guide
A three stone ring, also called a trilogy ring, sets one center stone between two smaller side stones. The side stones widen the look across the finger and add sparkle on each side of the center. The 3 carat figure is the weight of the center stone alone; the two side stones come in addition to it.
Round is the brightest and most classic shape. Oval, pear and marquise are longer, so the center looks larger and the row of three stones reads longer on the finger. Cushion, princess and radiant give lively sparkle in square or rectangular outlines. Emerald and Asscher are step cuts with a clean, mirror-like look, and heart is the boldest choice.
The band comes in widths of 1.8 mm, 2 mm or 2.2 mm; a slimmer band makes the stones look larger. Platinum is naturally white and hard-wearing and costs more than gold; gold comes in 10K, 14K or 18K white, yellow or rose gold. Prices start from about $2,400 in the lowest-priced metal, center included.
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.
Rings on this page start from about $2,400 in the lowest-priced metal, and that price includes the 3 carat lab-grown diamond center and both side stones. Platinum and 18K gold cost more than 10K or 14K gold, so the metal you pick sets the final price. Lab-grown diamonds cost far less than natural diamonds of the same size.
