Tennis Chain Buying Guide

The name comes from a bracelet, not from a link. A tennis bracelet is a single line of matched diamonds that moves with the wrist. A tennis chain is that idea long enough for a neck. Each stone sits in a setting, the settings are linked so the piece flexes, and the gold's job is to hold the stones rather than to be the look.

That is a different object from a Cuban, a rope, or a Franco. Those are gold links. A diamond Cuban is still a gold link, with stones added on the face. A tennis chain is stones first. If a photo could be either, ask which one it is before you talk about price. The side-by-side is Cuban link vs tennis chain.

Count the catalog before you get attached to the word. None of the 420 products has tennis in the title. The gold chain wall is 46 pieces of 10K, from $290 to $4,960, and they are plain gold. We are not going to relabel a curb and call it a tennis chain because both are worn on the neck. If you want this pattern made, it goes through custom: your idea, then a design and an exact price, and nothing is made until you agree. The gold patterns you can buy today are in chains.

Tennis pieces are sold by the width of the stone, in millimeters, because that is what you see. A 2 mm stone is a quiet line. A 3 mm stone is the everyday tennis look on a wrist and a noticeable line on a neck. A 4 mm stone reads clearly across a table. At 5 mm and above, the chain is the outfit.

Those widths are industry shopping language. They are not sizes we have in stock under this name, so do not hunt the site for a 4 mm tennis SKU. Use them to read someone else's listing, or to write a custom request that a jeweler can price. "A tennis chain" is not a request. "A 4 mm lab-grown diamond line, 18 inches, 14K white gold, box clasp with a safety" is a request.

Width and length multiply. A 4 mm line at 16 inches and a 4 mm line at 20 inches are not the same carat weight and should not be the same price if both are priced honestly. Compare chains at the same length. The size and carat chart stays on that math, including why we will not fake a millimeter-to-carat table.

Carat is weight. One carat is 200 milligrams, per GIA. A tennis chain's carat number is the sum of every stone. It is not the size of one stone. Two chains can both say 10 carats and look different if one uses fewer, larger stones and the other uses a long run of smaller ones.

We print total carat on diamond necklaces and bracelets that are not tennis chains. Use them as a lesson in reading the number, not as a substitute product.

Listed piece	Total carat	Price	About per carat, gold included
Round lab diamond necklace	9.18 ct	$5,300	$577
Round lab diamond necklace	18.48 ct	$6,500	$352
Round lab diamond necklace	30 ct	$8,950	$298
Round lab diamond bracelet	7.49 ct	$2,200	$294

The 30 carat necklace is not ten times the price of a smaller piece. Small stones in bulk do not price like a single center diamond. A tennis chain behaves the same way: more millimeters of stone raise the carats fast, and the price per carat often falls, until the stones get large enough to be priced one by one. Anyone selling you "10 carats" without the millimeter and the length is skipping the two numbers that create the 10.

The stone has to be named.

• Natural diamond costs more because the supply is mined. On a chain full of melee, that premium is real and it adds up stone by stone.
• Lab-grown diamond is the same carbon crystal, made in a factory. The FTC says the seller has to disclose it. It is the reason a diamond line can exist at a price a person actually pays. Our big diamond necklaces and the three lab diamond bracelets are lab-grown, and the titles say so.
• Moissanite and cubic zirconia are not diamonds. They can be bright. They cannot be described as a diamond tennis chain. We do not sell moissanite under any name.

Color and clarity still apply. For tiny stones, GIA's VS range is already past what the eye can pick out in a line of dozens. Chasing VVS on every melee stone in an 18 inch line is how the quote explodes without the chain looking different at arm's length. Put the money into matched color across the line. One stone that is visibly yellower than the rest will bother you more than a clarity grade you cannot see.

House pieces that carry a grade in our records, the lab and natural diamond rings and the large diamond necklaces, are E color and VS1 clarity. That grade belongs to those pieces. Do not copy it onto a tennis chain nobody has made yet. A custom line gets its own spec.

Settings are the hardware around each stone.

• Four-prong leaves more of the stone in the light. It also leaves the girdle exposed. A hard knock can chip an edge or bend a prong.
• Bezel or channel wraps metal around the edge. You see a bit less diamond and you snag less. On a chain that will hit zippers and collars, that trade is worth making.
• Shared prongs save metal and look continuous. If one prong fails, two stones feel it. Look at them under a light and make sure none is sitting higher than the row.

The clasp is not a detail. A tennis line is a series of small connections, and the clasp is the one you open every day. A box clasp with a figure-eight safety or a latch that clicks over the tongue is the standard Ross-Simons and other jewelers describe for this kind of piece. A tiny spring ring is for a light chain. It is a bad idea on a diamond line you would be sick about losing. Ask to see the safety closed, not just the render.

1. Walk the stones. Look down the line. Heights should match. A stone sitting tall will catch, and it will be the one that leaves.
2. Count, or get the count in writing with the total carat weight. "About 10 carats" is not an invoice line.
3. Name the origin on the same line: lab-grown or natural.
4. Name the metal. 10K is 41.7 percent gold, 14K is 58.3 percent, 18K is 75 percent. White gold is the usual metal under colorless stones because yellow shows through gaps. Yellow is a choice, not a mistake, if you asked for it.
5. Open and close the safety twice. If it is fiddly in the shop, it will be open in a cab.
6. Compare length. A cheaper chain that is 16 inches is not beating an 18 inch chain. It is shorter.

Our policy on pieces we do sell: insured shipping, 7 days to report a manufacturing defect, no refunds, sales final. Use that as the standard to ask for elsewhere too. A diamond line is a bad place to discover the return rule after a stone is missing and nobody wrote down how many there were.

Buy a gold chain if you want a gold chain. The Cuban buying guide and the gold Cuban links are that purchase, from $495 to $4,870. Buy a diamond necklace if you want stones we have already set and priced. The 18.48 carat lab necklace at $6,500 and the 30 carat one at $8,950 are those purchases. They are not tennis chains, and the photos will tell you so.

Commission a tennis line only if you can describe the millimeter, the length, the origin of the stones, and the clasp, and only after you have seen a price. We will not start from a screenshot and a budget shrug. Layering a finished diamond piece with a shorter gold chain has its own rules in how to layer chains. The diamond side of the case is also filed under tennis chains and diamond Cuban links when the design belongs there. Read the product title. The category name is not a promise that every photo is the same pattern.

Questions go to 954-504-5640. The showroom is at 7900 NW 27th Ave, Unit 506, Miami FL 33147. Bring the millimeter you want, not just the word tennis.
