Gemstone Shapes Explained: Round, Oval, Pear, Cushion and More

The shape of a gemstone dramatically affects how it catches light, how large it appears, and the overall character of a jewelry piece. Understanding gemstone shapes helps you choose the cut that best matches your personal style.

Round Brilliant

The most popular shape, engineered for maximum sparkle. With 57-58 facets, the round brilliant reflects more light than any other cut. Ideal for solitaire rings, stud earrings, and tennis bracelets.

Oval

An elongated version of the round cut that appears larger per carat weight. The oval shape creates a slenderizing effect on the finger, making it increasingly popular for engagement rings. Learn more in our carat weight vs size guide.

Pear (Teardrop)

A hybrid of round and marquise, the pear shape is elegant and distinctive. Beautiful in pendants and dangle earrings where the pointed tip can hang gracefully.

Cushion

A square or rectangular shape with rounded corners, giving it a pillow-like appearance. The cushion cut has larger facets that showcase gemstone color beautifully, making it ideal for colored stones like sapphires and emeralds.

Princess

A square shape with pointed corners and exceptional brilliance. The princess cut is the second most popular shape for diamonds and works beautifully in both solitaire and halo ring settings.

Emerald Cut

A rectangular shape with step-cut facets that create a hall-of-mirrors effect. Rather than sparkle, the emerald cut showcases clarity and depth. Popular for sophisticated cocktail rings and statement pieces.

Marquise

An elongated shape with pointed ends that maximizes carat weight. The marquise cut creates the largest surface area of any shape, making the stone appear bigger. Stunning in rings worn lengthwise along the finger.

Heart

The ultimate romantic shape. Heart-cut gemstones require skilled cutting to achieve perfect symmetry. Beautiful in pendants and sentimental jewelry pieces.

Which Shape Is Right for You?

Consider your style: classic (round, oval), modern (princess, emerald), romantic (pear, heart), bold (marquise, cushion). Also consider the setting — some shapes work better in three stone or cluster designs than others.
