Why choose a round brilliant diamond?

The round brilliant is cut with 58 facets engineered to maximise light return, making it the most sparkling and most popular diamond shape, and the classic choice for solitaire engagement rings and stud earrings.

How to choose a round lab-grown diamond

Cut grade. Cut matters most for round diamonds. Look for Ideal or Excellent cut, polish and symmetry for maximum brilliance; stones marked H&A (hearts and arrows) show a precise optical pattern.

Colour and clarity. D to F colour is the whitest; G and H look white once set and offer excellent value. VS1 and VS2 clarity are eye-clean.

How to choose a round diamond

Why choose a round?

The round brilliant has 58 facets designed to return as much light as possible, making it the most sparkling and most popular diamond shape, and the classic choice for solitaire engagement rings and stud earrings.

Cut

Cut matters most in a round. Look for Ideal or Excellent cut with Excellent polish and symmetry; a table of 54–60% and a depth of 59–63% return the most light, and stones marked H&A (hearts and arrows) show a precise optical pattern.

Colour and clarity

D to F is the whitest; G and H look white once set. VS2 and better look clean to the eye, and almost all of ours are VS2 or better. Every stone has a 360° video on its page, so you can see how clean it looks.
