Our Diamonds

Your diamond

So special
Every diamond on earth is unique, varying in size, colour and quality. At Promise Diamonds, we want your diamond ring to be the most beautiful it can be, so we make sure our collection consists of only the finest, certified diamonds.

Our collection
In order to fulfil this promise, we take our time to select each and every one of our diamonds by hand. This means our collection is of the highest standard so whatever diamond you choose, you can be confident in its quality and beauty. Take a look at our diamond engagement rings here.

Our range of stunning diamonds includes stones graded in colour from D to J as we consider these colours to be the best for jewellery. And in terms of clarity, they range from FL to S12 although some I1 diamonds still look fantastic and can save you money if you’re looking for a larger, whiter look. Please see our Diamond Education section, or call us for more information.

Conflict-free
We only buy our diamonds from the most reputable diamond suppliers in the world. They, like us, proudly adhere to and enforce the standards established by the Kimberly Process. All our diamonds are warranted to be conflict-free and we continue to support and promote any process that works to uphold legitimacy in the diamond trade.
