Marquise Diamond and Blue Sapphire Eternity Ring

Set with Marquise cut Diamonds and Round Brilliant cut blue Sapphires, this fully set Eternity Ring design is nothing short of elegant. With a total diamond weight of 0.80cts and a total Sapphire weight of 0.44cts, each stone has been expertly bezel set into the band, creating a practical rub-over setting for everyday wear. The Diamonds within your ring have been graded F Colour and VS1 Clarity before being expertly set into the unusual ring design. They will provide excellent purity and whiteness to the Diamonds. The band itself measures 2.9mm in width and has a traditional court profile. We can craft your ring in many precious metals for you, including 18ct Rose Gold, 18ct White Gold, 18ct Yellow Gold, Palladium and Platinum. Please allow us approximately four weeks to craft your ring for you in your chosen precious metal. Your eternity ring will then be delivered straight to your door by a secure courier, presented in our own Serendipity Diamonds packaging.

Diamond wedding rings and eternity rings.


Many buyers ask us the difference between diamond eternity and wedding rings. Our collection is divided into both categories to make searching easier. Most of our designs are, however, versatile. They can serve the purpose of either a diamond set wedding ring or a diamond eternity ring, depending on the occasion. 


Packaging and presentation.


We believe that presentation is an important part of your experience. As such, we provide beautiful pristine presentation boxes with all of our diamond jewellery. In addition, we deliver items in a large, secure outer box to protect your purchase. Watch our video below to learn more about how we present finished jewellery.
