Think you can use the words cut and shape interchangeably? Think again.
When it comes to diamonds, shape refers to the outline of the stone — round, oval, princess, etc. A diamond’s cut, on the other hand, refers to the arrangement of its facets, the angles, and the craftsmanship that influence how it reflects light.
In other words: Shape is what you see. Cut is how it sparkles.
Diamonds come in a wide range of shapes, and each one has its own personality, history, and way of catching the light. Whether you’re choosing a diamond for an engagement ring, a timeless pair of studs, or a keepsake pendant, understanding the different shapes can help you select the perfect piece.
