21K Gold Chains
6 pieces
“With gold, you're always dealing with money. So first decide how much of it you want to put into the gold.” Trax, at the jewelry store on 47th Street
Six chains in 21K yellow gold, from a 1.3 mm cable to a figaro past 3 mm, with rope and square wheat between.
Of the chains here, the 1.5 mm square wheat sold the most in the year, 11 in all.
21K gold chains at TraxNYC come in rope, square wheat, cable and figaro, 1.5mm to over 3mm. At 87.5 percent pure, the color runs deeper than 14K and the gram carries more gold.
Buyer's guide
How to choose a 21K gold chain
What 21K gold is, how a slim 21K chain wears, and which link and length to pick
Buy a 21K chain for its deep yellow, then wear it gently. At seven eighths pure gold it is softer than 14K or 18K, so a slim chain shows wear and can stretch sooner. Most of the chains here are fine, with one heavy figaro. Read the grams before the width, because the grams are the gold. For a chain worn every day, take a solid link of 2 mm.

Questions we get in the store
Do you have a thicker or heavier 21K gold chain?
The heaviest here is the solid figaro, listed at 12 grams, the only chain past 3 mm. For a wider rope or another 21K link, put the width and length in the live chat, or call or text 212-872-9692 from 10 AM ET.
What purity is 21K gold?
21K gold is 87.5 percent pure, which is 21 parts gold in 24. Silver and copper make up the rest and harden it. A 21K piece is usually marked 21K or 875, and every chain here is listed in 21K yellow gold.
Is a 21K gold chain durable?
It is, for gentle daily wear, but it is softer than 14K or 18K. A slim 21K chain can kink or stretch when it snags, so take it off for sleep and the gym. A solid link of 2 mm or more holds up best.
More questions we get
How many grams of gold are in a 21K chain?
Seven eighths of the weight on the listing. The figaro, listed at 12 grams, holds 10.5 grams of pure gold. A longer chain carries more, so ask the live chat for the grams at the length you want.
Can I hang a pendant on a 21K chain?
Yes, a light one. A bail slowly wears soft gold thin where it rubs, so put a small cross or charm on a 2 mm square wheat or rope rather than the finest cable. Make sure the clasp end slips through the bail.
What length 21K chain should I get?
Take 18 inches for the collarbone on most women and 20 for most men. Sixteen hugs the base of the neck, and 22 drops a little lower. Five of the six chains here come in 20 inches.
Does a 21K gold chain tarnish?
No. There is so little other metal in 21K that it keeps its yellow in ordinary wear. Chlorine and strong cleaners can still cloud the shine, so remove it before a swim and rinse it in warm water with mild soap.
Can I return a 21K gold chain?
Yes, within fourteen calendar days of delivery, unworn, unaltered and boxed. Clear it on the live chat first, then send it on our insured label. Five percent restocking and that label come off the refund. A chain shortened or lengthened for you is final.
How much is a 21K gold chain?
Each listing prints its own price, and it moves with the grams of 21K in the chain and the gold market on the day. For a width or length not listed, ask the live chat, or call or text 212-872-9692 from 10 AM ET.
