Buying guide
A solitaire is about the center, so the band sets the tone.
Pavé and halo stones add to the ring's overall weight; the 3.5 carat figure is the center alone.
Round gives the most sparkle and suits a classic solitaire. Oval, pear and marquise are longer and tend to look bigger for the weight. Emerald and Asscher are step cuts with a calm, mirror-like look that shows the stone's clarity openly. Cushion, princess and radiant are square or rectangular brilliants with lots of fire.
Gold comes in 10K, 14K or 18K, in white, yellow or rose. Platinum is naturally white and heavier. Prices start from about $3,150, and most rings sit around $3,450 to $3,500 in 10K gold, 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.
