Diamond Tennis Necklaces

A diamond tennis necklace is a flexible chain of individually set diamonds, joined so the stones form one unbroken line of sparkle. The name comes from the tennis bracelet, worn on court in the 1980s. Necklaces are made in straight-line form, with every stone the same size, or graduated, with larger stones at the centre. The look depends on total carat weight, stone shape, metal and length. Browse the full range on this page.

For everyday wear most people choose 16 or 18 inches. At 16 inches the necklace sits at the base of the neck and stays put under a collar. At 18 inches it rests just below the collarbone and works with most necklines. Choose 20 inches or more if you want it to layer or sit on the chest. Measure a necklace you already wear to see which feels right. For men, 20 to 22 inches is the most common range.

In a straight-line tennis necklace every diamond is the same size, giving a uniform line. A graduated necklace, often called a Riviera, uses smaller stones near the clasp that increase towards the centre, so the eye is drawn to the front. Graduated pieces tend to look more formal and more dramatic for the same total carat weight, while straight-line designs are easier to wear daily and to layer.

It depends on the stone size you want and your budget. About 4 to 8 carats gives a fine line suited to everyday wear. 10 to 15 carats shows distinct, sparkling stones. Beyond 18 carats the necklace becomes a statement. Carat weight is the total across all stones, so compare necklaces of the same length, and ask for the average stone size if you want to compare how large each diamond looks. Men's chains are often wider and carry more carat weight, so measure by chain width as well as carats.

Round brilliants give the most continuous sparkle and are the classic choice. Oval, pear and marquise stones lie lengthwise and create a longer, softer line. Emerald and baguette cuts give broad, clean flashes and a more architectural look. Mixed-shape designs add rhythm. If you will wear the necklace daily, rounds are the most versatile. Our designer necklaces collection shows fancy-cut and mixed designs in stock.

Most men choose a width between 3 and 6 millimetres. A 3 to 4 millimetre chain is a refined line that can be worn daily or layered, 5 to 6 millimetres is bolder and works worn alone, and 7 millimetres and above is statement scale. Length matters as much: 20 inches sits at the collarbone, 22 inches falls onto the chest and 24 inches hangs lower. Tell us your width and length and we will make it in any size.

Yes. Lab-grown diamonds are real diamonds with the same crystal structure, hardness and optical properties as mined stones. They are grown in controlled conditions rather than mined, which is why they are usually priced lower per carat. They are not cubic zirconia or moissanite. Each product page states whether the stones are lab-grown or natural, and our guide to lab-grown vs natural diamonds explains the differences.

Origin is the difference. Natural diamonds formed in the earth over billions of years and are mined. Lab-grown diamonds are created in a laboratory in weeks. They look the same to the eye and are chemically the same material. In practice, lab-grown usually offers more carat weight and higher grades for the budget, while natural carries rarity and provenance. Both are available here; you can filter the page by diamond origin.

Colour matters most for white metals and large stones, where tint is easiest to notice. Many of our lab-grown necklaces use D colour with VVS to VS clarity, and our natural necklaces range from F to D colour with VS to SI clarity. In a long line of small stones, the eye cannot see inclusions, so consistent colour and cut matter more than the highest clarity grade. Specifications are shown on every product page.

Usually not stone by stone, because a necklace can contain over a hundred small diamonds and laboratories report on individual stones or, for some jewellery, on the piece. Where a necklace is sold with a report, the product page names the laboratory and number. GIA grades natural diamonds and IGI grades lab-grown diamonds. If a certificate matters to you, ask us before you buy and we will confirm what applies to that necklace.

Yes. We are a leading UK name in men's tennis chains and sell over 500 every year, and we specialise in every size, length, metal and design: straight-line and graduated, round and fancy shapes, in 9K, 10K, 14K and 18K gold and platinum. Tell us your width, length in inches, carat weight and metal, and we can make it to order and deliver it in about three to four weeks.

Yes. Many listed designs come in several carat weights, which you choose on the product page. For any other specification, such as a particular carat weight, stone shape, length or metal, send us an enquiry. We can make any design to order and deliver it in about three to four weeks, and we confirm the price and timing in writing first. Bespoke and made-to-order pieces cannot be returned, so we agree the specification with you before we start. This applies to men's chains too, in any width and length.

9K gold is harder and more affordable, and it holds claws firmly under daily wear. 18K gold is richer in colour and more precious, and it is slightly softer. For a necklace worn often and layered, 9K is a practical choice. For a milestone piece or a warmer tone in yellow or rose gold, many people prefer 18K. Both are hallmarked in London, and white gold keeps the focus on the diamonds.

9K and 10K gold are the hardest wearing and suit daily wear. 14K and 18K gold have a richer colour, and platinum is naturally white and the densest of all, so a wide, long platinum chain is noticeably heavier. A heavier chain has more presence but sits with more weight on the neck, so ask us for the finished weight of the chain you are considering.

Bezel settings protect stones most because a thin metal rim surrounds each diamond. Crown settings hold each stone with a compact cluster of claws and sit low. Classic claw settings show the most light and are the traditional choice. Security depends on workmanship as much as design: evenly finished claws, strong links and a secure clasp with a safety catch. We check these before dispatch and in any service visit.

Yes. Our designer necklaces collection includes oval, emerald, pear, marquise and mixed-shape designs. If you want a particular shape that is not listed, send us an enquiry with the carat weight, metal and length you have in mind. We will check what is available through our diamond sourcing, and confirm the price and timing in writing before any commitment is made.

Yes. We can make and deliver any design in any length (in inches), carat weight and metal, including 9K, 10K, 14K, 18K gold and platinum, typically in three to four weeks. Tell us the length, total carat weight, diamond shape, metal and setting. We confirm what can be made, give a written quotation and agree the timing before we start. Custom pieces are designed and finished in our London workshop. Bespoke pieces are made to your specification, so they cannot be returned.

Your necklace is designed and finished in our London workshop, and precious-metal pieces are hallmarked in London before dispatch. Look for a secure clasp with a safety catch, and check that the links move freely when it arrives. If anything is not as it should be, contact us at once and we will put it right.

Price rises with carat weight, diamond quality and metal. Lab-grown necklaces start with fine 4 carat designs in 9K gold and rise through 10, 12 and 15 carat designs to statement pieces over 30 carats; natural diamond necklaces cost more than lab-grown at the same size, and platinum costs more than gold. The price on each product page is shown in your local currency and includes taxes where they apply. For a specific length, carat weight or metal, ask us for a written quotation.

Carat weight is only one factor. Natural diamonds cost more than lab-grown stones of the same size. Colour and clarity change the price, as does the metal: platinum costs more than 18K gold, which costs more than 9K. Setting, stone count, finished weight and the matching work in a long line also add or remove cost. Compare length, total carat weight, quality and metal together.

Our showroom is at 34 Greville Street, Hatton Garden, and we hold over 200 tennis chains in stock, so you can compare lengths, stone sizes and metals on your own neckline. Stock changes, so book an appointment and tell us which necklace, metal or carat weight you want to see. You can book through our appointment page.

Yes. Ready-to-ship necklaces are already made, finished and hallmarked, so they skip the time at the bench. They still go through final checks and secure packing, so allow a few days for dispatch. The estimated dispatch date is shown on each product page. Browse our ready-to-ship collection or tell us your date and we will show you what can make it.

Most made-to-order pieces take about two to three weeks, and the majority of our orders ship within about ten days. They are designed and finished in our London workshop and then sent for London hallmarking before dispatch. Specially sourced stones or unusual lengths can take longer. The estimated dispatch date on the product page is the figure to work to, and if you are buying against a fixed date, tell us at the start.

Yes. We ship worldwide, and we have a team supporting customers in the US and Europe. Delivery to the US and Europe typically takes three to four weeks, and our team helps you navigate import duties and taxes for your country. UK delivery is free by Royal Mail Special Delivery, insured until signed for. International orders go by FedEx or Royal Mail International at rates calculated at checkout.

We are a third-generation jewellery house that sources diamonds through the trade and makes its own jewellery in London. Buying direct means no extra retail layer between the stone and you, and the people advising you are the people who select and set the diamonds. You get a clear specification, a written quote for custom work, free cleaning, checks and servicing at our showroom, and a team that stays in touch and always offers returning customers our best value. We are also a leading UK specialist in men's tennis chains.

We source diamonds through the international diamond trade and sell direct, rather than buying finished necklaces for resale. Our diamond team sources from suppliers with among the lowest carbon emissions in the world, and we are targeting net zero by 2030. Buying direct means fewer layers between the stone and you, and a necklace can be built around a specification instead of a fixed catalogue.

Yes. Book a visit to our Hatton Garden showroom and we will lay out necklaces in the lengths and carat weights you want, so you can try them on. If you cannot visit, ask us for close-up photographs or a video of a particular necklace. We are happy to talk through the specification, the settings and the finish before you decide. Bespoke and made-to-order pieces are made to your specification and cannot be returned.

Lab-grown diamonds are graded by an independent laboratory. IGI grades our lab-grown stones, and where a piece is sold with a report the product page shows the number, which you can check on the laboratory's online tool. For a necklace of small stones we inspect and match the stones ourselves before setting. Ask us which documentation covers the exact necklace you are considering.

Yes. Book a private appointment at the showroom or send an enquiry through our enquiry page. Tell us your preferred length, carat weight, diamond shape, metal and budget, and a jeweller will reply with options and a written quotation. There is no obligation to buy. You can also call us on +44 20 8089 4040 or email sales@amadadiamonds.com.

Soak the necklace in warm water with a drop of mild washing-up liquid, brush gently with a soft toothbrush, rinse and dry with a lint-free cloth. Store it flat or hanging in a soft pouch, separate from other jewellery, and remove it before swimming, exercise or perfume. Cleaning, checks and servicing are free at our London showroom, so bring it in once a year to have the claws, links and clasp checked. Insure it on your home policy.
