Made To Last

The perfect engagement ring
The perfect engagement ring is like the perfect relationship. It needs plenty of sparkle and should be made to last forever. At Promise Diamonds, we use our experience in the industry, to combine beautiful diamonds with stunning ring designs to create award-winning engagement rings.

Welcome to Hatton Garden
At Promise Diamonds we cater for every taste and budget, and love offering advice for those at the beginning of their search as well as to those that know exactly what they want. Our door is always open – if you want to give us a call to ask a quick question, we’re happy to help. Or if you want to pop in to our premises in the world-famous jewellery centre of Hatton Garden in London, you’re always welcome.

Up to 70% off high-street prices
Our expert gemmologists hand-select only the best quality, certified diamonds and all our rings are hand finished. We believe jewellery deserves this kind of care, so we don’t treat it as an extra. In fact, because we work directly with suppliers and manufacturers, we offer all this for up to 70% off high street prices. On online purchases we promise 100% satisfaction or your money back: we’re confident you’ll love your ring, but if you don’t, we offer a 40-day refund.

Dream up a design
If you can’t decide on a piece from our collection, we are happy to work with you on a unique design of your own. Our highly qualified designers, mounters and setters are on hand to create a piece of jewellery inspired by your style with as much or as little guidance as you need.

Take your time
We know how challenging – and time-consuming – it can be to choose such an important gift, so if you want us to meet you at a location of your choice, we’re happy to do so. We can discuss your ideas at your convenience, with no pressure or rush to make a decision.

Get in touch
Whether you’re just toying with the idea of an engagement ring or nearly made your decision, any time is a good time to get in touch. Please call, send an email or request a call-back. At Promise Diamonds, we want to make life a little easier for you – and if we can add a touch of sparkle at the same time – then all the better.
