Buyer's guide
How to choose an 18K gold engagement ring
Settle the gold first, then what sits in the middle, then her size
Choose 18K for the deeper color, and plan on a polish now and then, because the softer gold shows wear sooner. Pick the gold color she already wears. Then decide the middle of the ring. Lab-grown centers here run near 3 carats, natural ones mostly under a carat, and a cluster of small diamonds skips the single stone altogether. Know her size before you buy, because a resized ring is final.

The middle center is of each row's rings that state a single center carat, and the lab-grown row counts the toi et moi, two stones on one ring, among its 27.
Questions we get in the store
Is 18K gold good for an engagement ring?
Yes, if she wants the deeper color and can live with a little wear. Its gold content runs higher than 14K, which makes it softer, so fine scratches show sooner and a jeweler polishes them away.
Lab-grown or natural diamond for an 18K engagement ring?
Either is a real diamond, so choose on size. Lab-grown centers here run near 3 carats and natural ones mostly under a carat. Nearly nine in ten center-diamond rings bought here in the year were lab-grown.
Which gold colors do these 18K engagement rings come in?
Nearly all come in yellow and white gold, and most in rose as well, picked on the listing. The cluster and baguette rings stop at yellow and white, and four listings offer no color choice, so ask the desk which gold it is.
More questions we get
Can an engagement ring have no center stone?
Yes. About half the rings bought here in the year had none. Their middles are small natural diamonds, most often a cluster in a square halo or baguettes set in a shape, and those designs weigh under 5 grams.
Does 18K white gold need replating?
Yes, now and then. White gold is pale gold under a rhodium plate that wears with daily use, and a jeweler renews it, usually every year or two. Yellow and rose 18K never need a plate.
What ring size should I order if the proposal is a surprise?
Order the size of another ring she wears, borrowed for a day and measured, or ask a friend or relative who will keep the secret. Check it against the ring size chart. Most rings here come in 5 through 8, half sizes included.
How fast does an 18K engagement ring ship?
A ring in stock usually leaves in two to five business days, insured. Several here are made to order in her size, and the 3 carat oval solitaire's listing allows about two to three weeks. Ask the desk which yours is.
Can I return an 18K engagement ring?
Yes, within 14 days of delivery, unworn and unaltered. Get the desk's clearance first, then ship on the store's insured label. Restocking takes 5 percent of the refund, and the label's cost comes off too. A resized or made-for-her ring is final.
How much does an 18K gold engagement ring cost?
Each listing prints its own price. Most of it rides on the center stone, its carat, its grades, and grown or mined. For a stone not listed, start in the live chat, or call or text 212-872-9692 from 10 AM ET.
