Round Brilliant Shape

The most iconic and sparkly of all shapes, known for its 58 facets and symmetrical brilliance. Perfect for solitaires and halo settings.

Princess Shape

A square shape with sharp corners and modern sparkle. It’s bold, geometric, and often chosen for contemporary settings.

Oval Shape

Elegant and elongating, the oval offers brilliance similar to a round, with a softer, stretched silhouette that flatters all hand types.

Cushion Shape

Vintage-inspired with rounded corners, the cushion cut has a pillow-like shape and can be soft or chunky, with lots of fire.

Emerald Shape

A sophisticated, step-cut rectangle with clean lines and hall-of-mirrors sparkle. Highlights clarity and is often used in Art Deco-style rings.

Radiant Shape

The best of both worlds: brilliant-cut sparkle with the shape of an emerald. Square or rectangular with trimmed corners—modern and dazzling.

Pear Shape

One end round, one end pointed—elegant, romantic, and ideal for making fingers look slender. Often set with the point facing up or down.

Marquise Shape

Elongated with pointed ends, this regal shape maximises carat appearance and gives a dramatic, vintage-inspired look.

9. Asscher

A square step cut with deep pavilions and a windmill-like facet pattern. Elegant and bold, it has vintage charm in spades.
