The brilliance and fire of a round diamond means if you're looking for sparkle, then this is the perfect engagement ring for you.

Round cut engagement rings are seen to be the traditional option for popping the question because the classic shape has a versatility that is suited to all engagement ring styles and is available in all three gold options as well as platinum.

ROUND BRILLIANT

Discover more about Round Engagement Rings

Did you know that more than 50% of all engagement rings sold across the world happen to hold a round brilliant cut diamond?


With a structure of 58 facets, round diamonds are cut to precision to guarantee the perfect light reflection and sparkle.

The round diamond is the only shape that comes with a certified "Cut" grade by a gemmologist. This refers to how perfectly the light reflects and refracts through the stone, showing off the life and dazzle of the stone.

The diamond cut grade is graded from Excellent to Poor. At Purely Diamonds, we only offer round diamond engagement rings that are graded either Excellent or Very Good. The latter comes as standard with all orders, however if you're looking specifically for an excellent cut diamond, then please do contact our team directly.
