Buying guide
A three stone ring holds one larger center with a smaller stone on each side. The side stones widen the look across the finger and add sparkle without a halo. The 2.5 carat figure is the center lab-grown diamond on its own; the two side stones are extra.
The center comes in round, oval, cushion, princess, emerald, asscher, radiant, pear, marquise and heart. A few points to weigh:
The band is slim, from about 1.8 to 2.2 mm, which keeps attention on the three stones and pairs easily with a wedding band. Platinum and white gold suit a bright look; yellow and rose gold warm it. The ring starts from about $2,000, center included, in the lowest-priced metal option.
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.
