A guide to diamond shapes.

A diamond’s shape changes the personality of a ring. Compare the outline, length-to-width ratio and how the stone looks in its setting.

Round brilliant

A circular outline and brilliant-style faceting make round diamonds a classic engagement-ring choice. Compare cut quality and dimensions alongside carat weight.

Oval

An oval has an elongated outline that can look graceful on the finger. Oval stones vary noticeably in length-to-width ratio. Inspect the exact stone for any darker bow-tie area across its centre and decide whether the overall appearance pleases you.

Emerald and radiant

Emerald cuts have step-cut facets and a hall-of-mirrors character. Their open table can make inclusions easier to notice. Radiants have a rectangular or square outline with brilliant-style sparkle. Compare corner proportions and length-to-width ratio.

Pear, cushion and princess

Pears taper to a point and work beautifully in rings and pendants; consider point protection and symmetry. Cushions can be square or elongated with soft corners and varied faceting. Princess cuts have a square outline and pointed corners that benefit from a protective setting.

Shape, carat and the finished design

Two one-carat diamonds of different shapes can have different face-up dimensions. Ask for millimetre measurements and a view of the exact diamond where available. Not every setting accepts every shape or carat size without a design change. Saffron will confirm feasibility and pricing in the quote.
