About the Round Brilliant Cut
The Round Brilliant Cut is designed to maximise brilliance, fire and scintillation through its symmetrical facet arrangement. Its classic shape and exceptional light performance make it one of the most popular and versatile choices for engagement rings and fine jewellery. Each diamond is carefully selected by us for its overall appearance and visual performance. Learn more about this classic shape in our Round Brilliant Diamond Shape Guide.
Independently GIA Certified
Every diamond is independently graded by the Gemological Institute of America (GIA) and supplied with its individual grading report.
The report confirms the diamond's carat weight, colour, clarity, cut grade, measurements and other grading characteristics. Its unique GIA report number is laser inscribed on the diamond's girdle, allowing the stone to be matched to its certificate.
Choosing Your Colour & Clarity
Choose from D, E, F and G colour grades, all within the colourless to near-colourless range.
VS1 & VS2 diamonds have minor inclusions that range from difficult to somewhat easy for a skilled grader to see under 10× magnification.
SI1 & SI2 diamonds have noticeable inclusions under 10× magnification, although their visibility to the naked eye varies between individual stones.
I1 diamonds have more prominent inclusions that may be visible without magnification and can affect transparency or brilliance.
Each diamond is selected with consideration for its overall appearance, helping you find a suitable balance of quality, visual performance and value.
How Big Is a 1.50ct Round Brilliant Diamond?
A 1.50ct Round Brilliant natural diamond typically measures approximately 7.4mm in diameter, although exact dimensions vary between individual stones.
Carat refers to a diamond's weight rather than its physical dimensions, so diamonds of the same carat weight can have slightly different face-up measurements.
Engagement Rings & Bespoke Jewellery
A 1.50ct Round Brilliant natural diamond is a versatile choice for engagement rings, earrings, pendants, accent stones and bespoke jewellery. Its classic shape works beautifully across solitaire, three-stone, halo and custom settings.
Whether you're choosing a diamond for your own jewellery or sourcing a stone for a client commission, we're happy to help with diamond selection and suitability for your chosen setting.
