Buyer's guide

How to buy 21K gold jewelry

Learn what 21K gold is and how it wears, then read the grams and pick your size

Choose 21K for its deep yellow and the gold in it, and wear it with care. It is seven eighths pure gold and softer than 18K, so it shows wear sooner. Read the grams on each listing, because the weight tells you how much gold you get. The case is small, mostly bangles and a few chains. Every bangle is 2.5 inches across. For another size or a longer chain, ask us.

21K gold: what 21 karat gold means and how pure it is

21K gold is 87.5 percent pure gold. Karats count gold in 24ths, and 21K is 21 of them. The last eighth is other metal, mostly silver and copper, which hardens the gold and sets its color. Some 21K pieces are stamped 21K or 875 and some are not. Every piece here is listed in 21K yellow gold, and none says plated.

Karats: 21K vs 18K vs 22K vs 24K gold

Take 21K when you want the color of high-karat gold in a piece you can still wear. Beside 18K, which is three quarters gold, it is a deeper yellow and softer, and it takes scratches and dents sooner. 22K is a shade deeper and softer again. 24K is pure gold, the richest color, and a thin piece of it bends in the hand. 21K will not tarnish in ordinary wear, since so little of it is other metal. Take it off for the gym and heavy work. The table below sets the karats side by side, with 14K for scale.

Grams: how much gold is in a 21K gold chain or bangle

Seven eighths of the weight on a listing is pure gold. A 7-gram bangle holds about 6.1 grams of it, so read the grams before the width. The same design weighs more in 21K than in 14K, because gold is heavier than the metals mixed into it. The bangles here run from 5 to 12.5 grams. The two heaviest are slim ones, and several wide bangles weigh less than any slim one. The chains run from 1.5 grams for the fine cable to 12 for the figaro.

Bangles: 21K gold bangles, bangle size and weight

Every bangle here comes in one size, 2.5 inches across, so measure your hand first. No listing names a clasp or a hinge, and a bangle without one has to slide over the hand. Tuck your thumb toward your little finger and wrap a tape around the widest part of your hand. A 2.5-inch bangle clears a hand that measures up to about 7.8 inches. Most of the nine carry a pattern or a twist, which hides the fine scratches soft gold picks up. Worn together, 21K bangles rub and mark each other. Ask the desk about any other size.

Chains: 21K gold chains, width and length

The chains here run from 1.5 to 3.2 mm. None comes longer than 22 inches, and 20 is the length bought most. On most women, 16 inches sits at the base of the neck. Eighteen reaches the collarbone. Twenty falls just below it, and sits near the collarbone on most men. Keep a pendant light on a fine 21K chain, since soft gold wears thin where the bail rubs. For a longer chain or a wider rope, put the length and width in the live chat, or text 212-872-9692, read by a person from 10 AM ET.

Karat: how much gold each karat holds, its color and how it wears

Karat	Pure gold	Stamp	Color	Wear
14K	58.3%	585	Light yellow	Tough
18K	75%	750	Rich yellow	Firm
21K	87.5%	875	Deep yellow	Soft
22K	91.7%	916	Deeper yellow	Softer
24K	99.9%	999	Deepest yellow	Softest

Every count on this card is from the 14 pieces live here on September 26, 2026 and what this page sold in the year to that day; prices are on the listings. The karat rows are the standard for yellow gold, and the stamp is the gold in thousandths.

Questions we get in the store

Is 21K gold real gold?

Yes. 21K is 87.5 percent pure gold, with a little silver and copper mixed in to harden it. A 21K or 875 mark depends on the piece. All fourteen pieces here are 21K yellow gold by their listings, and none says plated.

Is 21K gold better than 18K or 22K?

Neither is better, because each karat trades color against hardness. 21K is a deeper yellow than 18K and softer. It is a touch paler than 22K and a little harder. Take 18K for fine detail you wear hard, and 21K for the color.

Can I wear 21K gold every day?

Yes, with some care. It dents and scratches more easily than 14K or 18K, so take it off for the gym and for heavy work. It will not tarnish, and a patterned piece hides the fine marks better than a mirror polish.

Does 21K gold tarnish or change color?

No, not in ordinary wear. So little of 21K is other metal that it keeps its color. Pool chlorine and harsh cleaners can still dull the surface, so take it off to swim and wash it in warm, soapy water.

What do the grams on a 21K listing tell me?

They weigh the whole piece, and seven eighths of that weight is pure gold. Compare two pieces by their grams, since pieces of the same width can weigh very differently.

What size are these 21K gold bangles?

Each is 2.5 inches across, and that is the only size listed. Tuck in your thumb and measure around the widest part of your hand. If the tape reads about 7.8 inches or less, the bangle should slip over. For another size, ask us.

Can I get a longer 21K chain or a piece not listed?

Ask the desk. This page holds every 21K piece we list, and its chains stop at 20 inches. Put the length or the piece you have in mind in the live chat, or text 212-872-9692, answered by a person from 10 AM ET.

Can I return a 21K gold piece?

Yes, for fourteen calendar days after delivery, unworn, unaltered and in its box. Clear it with customer service at service@traxnyc.com or 212-391-3832 before it ships back, and use only our return label. The refund policy deducts five percent restocking and that label. Sized or custom work is final.
