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 Cut grade itself is graded from Excellent to Poor. The good news is that at Purely Diamonds, we only offer round diamonds 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.
