Diamond Cut
RINOVA Diamond Guide
Diamond Cut
Of all the 4Cs, cut has the biggest impact on a diamond's sparkle. It measures how well the facets return light to your eye — as brilliance, fire and scintillation.
Cut Grades
A well-cut diamond outshines a larger one with a poor cut. We recommend prioritising cut.
FairGoodVery GoodExcellent
- Excellent / Ideal — maximum light return and sparkle; our recommended grade.
- Very Good — excellent brilliance at a slightly better value.
- Good — reflects most light; a budget-friendly choice.
- Fair — noticeably less sparkle; generally not recommended.
Why Cut Matters Most
Color and clarity describe what a diamond is made of, but cut determines how it performs. A precisely cut diamond dances with light — which is why we treat cut as the foundation of every RINOVA stone.
