Put simply, Seventy Seven is a reference to the year 1477, when the modern Western form of the practice of giving or exchanging engagement rings begun. The first diamond engagement ring was given to Mary of Burgundy by Archduke Maximilian I of Austria. We just thought Fourteen Hundred and Seventy Seven Diamonds was a bit of a mouthful.

Originating from Canada, Russia, Australia and Africa our diamonds are sourced direct from the mines. They are expertly polished and sent to trusted laboratories for certification before being displayed on our website.
All are conflict free and comply with the industry’s strict Kimberley process regulations. You won’t find any blood diamonds here.
We are committed to providing you with access to the highest quality jewellery, diamonds and service at the best possible prices.
We achieve this by combining leading jewellery designs, top class craftsmanship and direct access to the highest quality diamonds. That means you can purchase products at least the equal of those from top High Street jewellers, but at a significantly reduced price.
