About the Oval Cut
The Oval Cut combines brilliant-style faceting with an elegant elongated outline, offering excellent brilliance and generous face-up coverage. Its length creates a flattering appearance on the finger, making Oval diamonds particularly popular for engagement rings and solitaire settings. Each diamond is carefully selected by us for its overall appearance and visual performance. Learn more about this distinctive shape in our Oval Diamond Shape Guide.
Independently IGI Certified
Every diamond is independently graded by the International Gemological Institute (IGI) and supplied with its individual grading report.
The report confirms the diamond's carat weight, colour, clarity, measurements and other grading characteristics. Its unique IGI report number is laser inscribed on the diamond's girdle, allowing the stone to be matched to its certificate.
Choosing Your Clarity
Choose from VVS2, VVS1, Internally Flawless (IF) and Flawless (FL) clarity grades.
VVS2 & VVS1 offer exceptionally high clarity, with inclusions that are extremely difficult to see under 10× magnification.
IF (Internally Flawless) diamonds have no internal inclusions visible to a skilled grader at 10× magnification.
FL (Flawless) is the highest clarity grade, with no inclusions or blemishes visible to a skilled grader at 10× magnification.
For most customers, VVS clarity already provides an exceptionally clean appearance, while IF and FL are suited to those looking for the highest clarity grades.
How Big Is a 3.00ct Oval Diamond?
A 3.00ct Oval lab grown diamond typically measures approximately 11.5 × 8mm, 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 3.00ct Oval diamond is an excellent choice for engagement rings, pendants and bespoke jewellery. Its elongated shape works beautifully across solitaire, halo, three-stone 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.
