Every purchase comes with an official appraisal: carat and gram weights, diamond grade and color, current market value, and our corporate seal.

A gold piece is priced from four things: its weight in grams, the share of pure gold in its karat, the gold price, and the work in it.

Today’s gold price

If the piece is in the store, your rep can show it to you on video; for made to order, the closest piece we have.

18K gold necklaces for women: 75% pure gold with a deeper yellow than 14K, offered in yellow, white or rose on most listings. Most are set with diamonds: baguette and pear diamond necklaces, hearts and butterflies, flowers and halo drops, crosses, Star of David and hamsa pendants, plus fine 18K cable, anchor and rolo chains.

“Buy jewelry you fall in love with: something that makes you happy every time you put it on.” Trax, at the jewelry store on 47th Street

All 80 pieces here are 18K, white gold on 75 and rose on 53; most of what sold weighed 2 to 5 grams.

The baguette diamond heart sold most in the year, 13, then a 9 mm round diamond on an adjustable chain, 9.

Buyer's guide

How to choose an 18K gold necklace

Check whether a chain comes with it, then pick the length, the grams and the gold color

Buy 18K for the deeper yellow and the diamond pieces, and wear it with a little care. Before you pay, check that the listing names a chain length, because a piece called a pendant may come without one, so ask us. Most of what people bought weighed 2 to 5 grams, and 18 inches is the chain length named most.

18K or 14K: is 18k gold good for a necklace

Yes, if you treat it with a little care. 18K is 75 percent gold, so the yellow runs richer and the surface is softer than 14K. A necklace rubs against far less than a ring or a bracelet does, so the softer gold suits it. Every listing here gives its gold as 18K, and all ten chains call themselves solid. An 18K or 750 stamp near the clasp or bail depends on the necklace. For a chain that takes knocks at work or the gym, look at 14K gold necklaces, the harder alloy.

Chain included: does an 18k gold pendant come with a chain

Look for a chain length on the listing before you pay. Of the 70 pieces that are not chains, 34 name one, by a length menu or a stated length, and hang on that chain. The other 36, mostly crosses, stars and hamsas, may come alone, so plan a chain or ask us. Three titles promise an adjustable chain. For a pendant on its own, the eight fine chains here run 1.6 to 2.8 mm, in 18 or 20 inches, white or yellow. Keep the chain the same gold color as the pendant.

Length: 16 or 18 inch 18k gold necklace

Take 18 inches if you are not sure. On 18 of the 20 necklaces with a chain length menu it is the only choice, and those listings took about half of the year's pieces. At 18 a small drop rests on the collarbone. Sixteen sits closer, near the base of the neck, and several necklaces are made at that length. Two sets reach 24. For 22 inches on a plain chain, ask us first, because we cannot take back a chain cut down or extended for you. Our length chart walks through each one.

Grams: how many grams is an 18k gold necklace

Two to five grams is where most buyers landed, about three quarters of the pieces sold, and the middle piece sold weighed close to 3 grams. The five 9 mm diamond drops weigh 2.4 to 4 grams and sold a quarter of everything. The lightest piece is a 0.8-gram round cut cross. Past 10 grams a pendant turns into a statement, and the two heaviest pieces weigh 105 and 158 grams. Grams are printed on 78 of the 80 listings, so ask whether a necklace's weight counts its chain before you compare two.

Diamonds and color: 18k white, yellow or rose gold diamond necklace

Most pieces here carry diamonds, and baguettes led the year, with nine baguette listings selling a third of the pieces. The heart was the shape bought most, as six hearts took nearly a quarter by count. Three titles name a lab-grown center diamond, and the other diamond pieces give their stones as natural. White gold is offered on 75 pieces, yellow on 73 and rose on 53, and 53 come in all three. One Jesus pendant is 18K green gold. More hearts in every karat are on women's heart necklaces.

Every count on this card is from the 80 pieces live here on October 13, 2026 and what this page sold in the year to October 12, 2026; prices are on the listings. Middle weight is the median of the grams each kind prints. Chain named means the listing gives a chain length, by a menu or a stated length.

Questions we get in the store

Does an 18K gold pendant come with a chain?

Yes, when the listing names a chain length, by a length to pick or a stated length, as 34 of the 70 pendants and necklaces do. A piece with no length named may need a chain, so ask us before you pay.

Can I get an 18K necklace in 20 or 22 inches?

Yes on a few. Two sets offer 20 and 22 inches, and some plain chains come at 20. For any other piece, ask us before you order, since a chain shortened or lengthened just for you is final sale.

Do the grams on an 18K necklace include the chain?

That varies by listing, so ask us, since each prints a single weight. For a necklace, that figure may cover the drop by itself or the drop and its chain together. On a plain 18K chain, the grams are for the chain alone.

More questions we get

Can I wear an 18K gold necklace every day?

Yes, with some care. Put it on after perfume and lotion, take it off for the gym, the pool and bed, and store a fine chain apart so it cannot tangle.

Is an 18K gold necklace real gold, or plated?

Real gold. 18K means 75 percent gold, all 80 listings give 18K as their gold, and none is titled plated, filled or vermeil. Note that the green gold Jesus pendant's description pairs it with a sterling silver chain.

Are the diamonds natural or lab-grown?

Natural on most pieces, by their listings. Three titles say lab-grown, two ovals and a halo drop, and on those the center diamond is lab-grown and the smaller ones natural. A lab-grown diamond is a diamond, graded on the same scale.

Should I choose white, yellow or rose 18K gold?

Match the gold she already wears. White is offered on 75 of the 80 pieces, yellow on 73 and rose on 53, so most let you pick. All three hold the same 75 percent gold, and the metals mixed in set the shade.

Can I return an 18K gold necklace?

Yes, unworn and unaltered, within fourteen days after delivery. Clear it with customer service at service@traxnyc.com or 212-391-3832. We send our return label and keep five percent restocking plus return shipping. Photo pendants and resized chains are final.

How much is an 18K gold necklace?

Each listing prints its own price. The grams of gold, the diamonds and whether a chain comes with the piece set it. For a quote, ask the live chat, or call or text 212-872-9692 from 10 AM ET.

About this collection
ABOUT THIS COLLECTION

18K Gold Necklaces for Women: Baguette, Heart, Butterfly and Cross

The facts, from our listings

  • Gold: 18K on every piece, 75% gold; most offered in yellow, white or rose.
  • Stones: diamonds on most, natural or lab-grown; ruby, sapphire and pearl pieces too.
  • Styles: crosses and Star of David pendants, baguette and heart necklaces, butterflies, flowers and halos.
  • Chains: fine 18K cable, anchor and rolo chains, the cable from 1.6 mm.
  • Length: 16 to 22 inches on most; 18 inches is offered most.
  • Weight: the grams are on nearly every listing.

Is 18K gold good for a necklace worn every day?

Yes, with a little care. A necklace takes less wear than a ring or a bracelet, so 18K's softness shows less; keep a fine chain apart from heavier pieces so it does not scratch or knot.

Do 18K necklaces come in white gold?

Most listings let you choose 18K white, yellow or rose gold for the same piece, and a few are made in white gold only.

Does an 18K pendant come with a chain?

A piece listed as a necklace comes on its chain. A pendant listed alone needs one; the fine 18K cable chains on this page fit, and 18K gold pendants has more pendants.

More 18K chains for men and women are on 18K gold chains. The same styles in 14K: 14K gold necklaces; every karat for women is on women's gold necklaces. Read how the karats compare in 10K vs 14K vs 18K. For him, see our gold cross necklace for men.
