Diamond Jewelry United is a UK jeweller run by Steven Grunhut, a third-generation diamond jeweller who has been selling diamond jewellery online since 2007.
We offer a wide range of fine jewellery in both natural and lab-grown diamonds, including engagement rings, eternity rings, earrings, pendants, necklaces and bracelets. Every piece is solid gold and made by our own manufacturer, who designs exclusively for us, so you won't find our designs anywhere else.
Our aim is simple: beautiful new jewellery at the kind of prices you'd normally expect to pay for pre-owned. Because we work directly with our manufacturer, our prices are among the most competitive online, without cutting corners on quality.
Buy with confidence:
- Every natural diamond comes with a GIE certificate, and lab-grown diamonds over 1 carat come with an IGI certificate
- An in-house valuation is included with every purchase
- Rings are sized to fit, so just choose your size when you order
- Free worldwide priority shipping, with fast dispatch from the UK
- 60-day returns, with a prepaid, insured return label
