The Best Diamond Necklace Stores in London (2026 Guide)
London is one of the world's great destinations for fine diamond jewellery — and nowhere is that more evident than in its extraordinary range of diamond necklace stores. From the certified diamond specialists of Mayfair to the heritage luxury houses of Bond Street and the independent boutiques of Knightsbridge, the city offers an unmatched depth of choice for every taste and budget.
In short: London's diamond necklace retailers concentrate in Mayfair (heritage luxury houses like Tiffany, Cartier, Boodles), Bond Street (David Morris, Graff, Garrard), and Hatton Garden (independent specialists and Reve Diamonds). Mayfair and Bond Street brands carry 40-60% brand premium; Hatton Garden delivers comparable quality at significantly lower prices. Most pendants run £800-15,000 depending on stone size and origin.
Whether you're looking for a classic diamond solitaire pendant, a pavé diamond collar, a bespoke commissioned piece, or a statement necklace from one of the world's most prestigious jewellery houses, this guide covers the best stores in London for diamond necklaces — and everything you need to know before you buy.
