Emerald cut gemstones are rectangular step cuts with clipped corners and long, open facets. Instead of sparkle, they give a calm hall-of-mirrors look that suits emerald, aquamarine, tourmaline and other richly coloured stones.
How to choose an emerald cut gemstone
- Prioritise clarity: the open facets show inclusions more than brilliant cuts do.
- Pick a length: a longer rectangle looks sleek, while a squarer one feels classic.
- Inspect the corners: clipped corners protect the stone, so make sure none are chipped.
- Look for even colour: step cuts make colour zoning easier to see.
- Choose a rich colour: the cut shows colour depth well, so pale stones can look washed out.
