Emerald Cut
The emerald cut is a rectangular step cut with cropped corners and long, mirror-like flashes — understated, architectural and timelessly elegant.
What is an emerald cut?
An emerald cut is rectangular with cropped corners and long parallel facets cut in steps. Rather than sparkle, it gives broad flashes of light. It was first developed to protect brittle emeralds, and is now popular for diamonds and other stones.
History & why it matters
Its clean lines suited the geometry of Art Deco, and it remains a refined choice for engagement rings.
What affects value
As a step cut it hides little, so clarity and colour matter. With antique diamonds, the period setting adds value. Browse diamond jewellery or read about gemstone cuts.
