Diamond Tennis Necklace

A diamond tennis necklace like this one is the timeless essential of the range: a continuous line of diamonds, each held in an open claw setting, in the classic silhouette that gave the style its name. It's built to be worn daily, not saved for one night, and it's usually the first piece people add when they're starting a fine jewellery collection.

A Diamond Tennis Necklace in Solid Gold

Every diamond is set in an open claw along a flexible chain, which is what gives a tennis necklace its fluid movement at the neckline. It's the piece the rest of the range is measured against, the one to start with if you're building a collection, and the one every other tennis necklace here takes its cue from.

The Design Detail of This Diamond Tennis Necklace

Brilliant-cut diamonds run in an unbroken line, each one individually set to keep the chain flexible rather than rigid. That flexibility is what lets it move with you and sit naturally at the neckline, rather than sitting stiffly in one place.

Solid Gold & Diamond Tennis Necklace, Hallmarked

Made in solid 9ct, 14ct or 18ct gold, hallmarked in the UK, set with natural, ethically sourced diamonds. Never plated. The claw setting is built to hold each stone through years of daily wear, not just for the day you unwrap it.

How to Style Your Diamond Tennis Necklace

Worn alone with an open neckline, it needs nothing else to make its case. Layer it with fine gold chains or necklaces of varying lengths for daytime, and let it move into evening exactly as it is, rather than swapping in another tennis necklace from the collection. It's the one piece here that genuinely works with everything else you own.
