Buying guide
Karat tells you how much pure gold is in the alloy. 10K is the hardest wearing and the lowest priced, with a lighter color. 14K balances durability and color and is the most common choice for engagement rings. 18K holds more gold, so yellow and rose look richer, and it costs more. White gold is plated to stay bright and may need replating over the years.
A 1.5 carat center is large enough to carry a simple plain band, and a rounded band softens the profile. Pave, halo and hidden halo designs add small lab-grown diamonds for more sparkle. The three stone ring and the marquise or pear side-accent styles spread the look across the finger, and the cathedral design lifts the center over a graduated pave band. Those accents add to the ring's total; the 1.5 carat figure is the center.
Round shows the most sparkle. Oval, pear and marquise look larger from the top for the same weight. Princess, asscher and cushion give a squarer outline, and emerald and radiant offer a rectangle with different facet styles. Heart is the most romantic and least common.
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.
At RJ, 1.5 carat gold rings start at about $1,100, and most cost between about $1,275 and $1,400 in the lowest-priced gold, with the lab-grown diamond center included. Choosing 14K or 18K gold raises the price, and halo, pave and three stone styles usually cost a little more than a plain solitaire. Every ring is made to order in 10–15 days.
