Diamond Tennis Bracelet: A Complete Buying Guide

A diamond tennis bracelet is a continuous line of diamonds set in a flexible chain. It is elegant, versatile and often given as a gift for a milestone. This guide explains what to look for so you can choose a bracelet that is beautiful, comfortable and secure.

What is a tennis bracelet?

A tennis bracelet is a slim, flexible bracelet with a row of evenly sized diamonds. The name is often linked to the tennis player Chris Evert, who stopped a match at the 1987 US Open when her diamond line bracelet fell off, after which the style became known by this name. Today it is a classic of fine jewellery.

Decide on the total carat weight

Tennis bracelets are described by total carat weight, which is the combined weight of all the diamonds. A bracelet with a higher total weight has either larger stones or more of them. Because there are many diamonds, the size of each one varies and affects the look. A bracelet with smaller stones appears delicate, while one with larger stones looks bold. Ask for the number of stones and the approximate size of each.

Check diamond quality

For a bracelet, matching is important. The stones should be consistent in colour, clarity and brightness so that the line looks even. Because the stones are small and seen in a row, many buyers choose near-colourless grades and clarity that looks clean to the eye instead of the very highest grades. Ask whether the diamonds are natural or lab-grown, and what colour and clarity range is used. Our guide to diamond clarity grades and the 4Cs explains the terms.

Choose the setting

The setting affects the look, comfort and security of the bracelet.

• Prong or basket setting: diamonds are held by small prongs, letting plenty of light in.
• Illusion setting: a small metal plate around each stone makes it appear larger.
• Bezel setting: metal surrounds each diamond for a smooth and secure look.

Ask how securely the stones are set, as a bracelet gets a lot of knocks on desks and clothing. Look for settings that sit low and are well finished.

Pick the metal

Yellow gold, white gold, rose gold and platinum are common choices. White metals tend to make diamonds look bright, while yellow and rose gold add warmth. Check the gold karat or metal purity, and ask about plating on white gold. Our guide to white, yellow and rose gold can help you decide.

Consider the clasp

A secure clasp is vital. Many tennis bracelets use a box clasp with a built-in tongue, often with an additional safety latch or figure-eight catch. Test that the clasp closes firmly and is easy for you to fasten. A bracelet that is hard to fasten may be difficult to wear daily.

Get the length right

A tennis bracelet should be snug enough that it does not slide too far but loose enough to be comfortable and flexible. Measure your wrist with a soft tape and add a small amount for comfort, often around half an inch, then compare with the bracelet length. Common lengths are around 6.5 to 7.5 inches, but check the size for each piece. Our tennis bracelet length guide gives detailed steps.

Natural or lab-grown

Both are real diamonds. Lab-grown stones are typically less expensive, which can make a higher total carat weight more affordable. Natural diamonds are valued for their origin. The seller should clearly state which type the bracelet uses. See our guide to lab-grown versus natural diamonds for more.

Think about comfort and everyday wear

Tennis bracelets can be worn daily if they are well made. Look at how the links move, whether the edges are smooth and whether the clasp catches on clothing. If you wear a watch, consider how the two will sit together.

Care and maintenance

Clean the bracelet gently with warm water, mild soap and a soft brush, and dry with a lint-free cloth. Check the stones and clasp regularly for looseness, and have the bracelet inspected by a jeweller from time to time. Store it flat or in a soft pouch. Our guide to cleaning diamond jewellery at home explains the steps.

Questions to ask before you buy

• What is the total carat weight and how many stones are there?
• Are the diamonds natural or lab-grown?
• What are the colour and clarity ranges?
• What metal and purity are used?
• What type of clasp does it have, and is there a safety latch?
• What are the warranty, returns and repair policies?

Gift considerations

A tennis bracelet is a popular gift for anniversaries and birthdays. If you do not know the wrist size, choose a seller that offers adjustments or exchanges, and check the policy before you buy.
