In this guide, we cover everything you need to know about choosing the best diamond tennis necklace — including classic diamond, lab grown diamond, and the best options available on Amazon with trusted reviews and fast delivery.

What Is a Diamond Tennis Necklace?

A diamond tennis necklace follows the same design philosophy as the iconic tennis bracelet — a continuous line of individually set diamonds in a flexible, symmetrical chain. The name "tennis" comes from the sport's association with elegant diamond line jewellery, popularised when Chris Evert stopped a 1987 US Open match to find her lost diamond bracelet — the moment that gave the style its name.

Tennis necklaces typically feature round brilliant-cut diamonds set in white gold, yellow gold, rose gold or sterling silver, with a secure clasp. They range from delicate, subtle styles to bold statement pieces depending on carat weight and chain length.

Diamond Tennis Necklace vs Lab Grown Diamond: What's the Difference?

The same principles that apply to diamond tennis bracelets apply here:

• Natural diamonds — mined from the earth, formed over billions of years; the traditional choice with established resale value
• Lab grown diamonds — chemically, physically and optically identical to natural diamonds; created in a controlled environment; typically 50–70% less expensive than natural diamonds of the same quality
• Lab created diamond tennis necklace — the same sparkle, the same hardness (10 on the Mohs scale), the same certification — at a fraction of the price

For most buyers, a lab grown diamond tennis necklace offers exceptional value — a real diamond necklace at a price that makes the style genuinely accessible.

How to Choose the Right Diamond Tennis Necklace

Chain Length

• 14–16 inches — choker/collarbone length; sits high on the neck; elegant and modern
• 17–18 inches — the most popular length; sits just below the collarbone; versatile for all necklines
• 20+ inches — longer, more dramatic; works beautifully with open necklines and evening wear

Metal Type

• White gold — the most popular choice; enhances diamond brilliance; available in 10K, 14K and 18K
• Yellow gold — classic and warm; pairs beautifully with champagne or fancy yellow diamonds
• Rose gold — romantic and modern; increasingly popular for tennis necklaces
• Sterling silver — the most affordable option; beautiful but requires more maintenance
• Platinum — the most durable and prestigious; naturally white and hypoallergenic

Carat Weight

• 1–3 CTW — delicate and subtle; ideal for everyday wear
• 3–6 CTW — the most popular range; noticeable sparkle without being overwhelming
• 6–10+ CTW — statement piece; significant sparkle and presence

Clasp & Security

A secure clasp is essential for a tennis necklace — look for a lobster clasp or box clasp with a safety latch. Given the value of the piece, always check that the clasp mechanism is robust before purchasing.

Lab Grown Diamond Tennis Necklace: Is It Worth It?

For most buyers — absolutely yes. A lab grown diamond tennis necklace gives you a real diamond necklace with IGI or GIA certification at 50–70% less than a comparable natural diamond piece. The only meaningful difference is resale value. If you're buying to wear and enjoy, lab grown is exceptional value.

Diamond Tennis Necklace as a Gift

A diamond tennis necklace is one of the most universally appreciated jewellery gifts for women — suitable for birthdays, anniversaries, Christmas, Valentine's Day, or any occasion that deserves something truly special. Pair it with a diamond tennis bracelet for a complete, matching set that will be treasured forever.
