Steven Stone

Steven Stone is a family jeweller established in 1937, now run by the third generation. The website carries a full range of settings with express delivery on stock pieces (quoted at one to two working days), and a bespoke service lets you design a ring with a diamond specialist. The house works with GIA-certified diamonds, and offers a virtual consultation for buyers who cannot visit in person.

Showrooms are in London, Manchester and Cheshire. The company also offers a price-match if you find a like-for-like diamond cheaper elsewhere on the high street.
