Emerald Cut
The emerald cut is a rectangular step-cut diamond with a large open table and cropped corners, giving elegant flashes rather than intense sparkle.
The emerald cut is a rectangular diamond with long, straight facets cut in steps and corners that are cropped at an angle. It has a large, open table on top. Rather than fiery sparkle, it produces broad, mirror-like flashes of light, an effect often called the hall of mirrors, which gives it a restrained, elegant character.
The step-cut hall of mirrors
Where a brilliant cut has small triangular and kite-shaped facets for scattered sparkle, the emerald cut uses long parallel facets that run like steps down toward the culet. When you look into the stone, these rows create alternating light and dark bands that flash as the diamond moves. The look is understated and architectural rather than sparkly.
The cropped corners give the outline its distinctive elongated octagon shape and also make it more durable, since there are no sharp points to chip. The overall effect suits Art Deco and vintage-inspired designs, and the long lines can make a finger look slender.

- Large open table and an elongated octagonal outline
- Broad hall-of-mirrors flashes, not intense sparkle
- Cropped corners make it durable
Why clarity and colour matter more
The large open table is honest to a fault. With so little facet activity to distract the eye, inclusions and body colour show more readily than in a brilliant cut. A crystal that would hide in a round can be clearly visible under the table of an emerald cut, so buyers usually prefer VS2 or better clarity and hold to a higher colour grade to keep the stone looking clean and white.
That transparency is also part of the appeal for those who love a clear, glassy stone: an eye-clean, high-colour emerald cut has a calm clarity that a busy brilliant cut cannot match. Because it retains weight efficiently, it can also look large for its carat, though its face-up size and open look mean quality has nowhere to hide.

Emerald Cut, in short.
Why does an emerald cut show less sparkle?
Its long step facets create broad flashes of light rather than the scattered sparkle of a brilliant cut. The effect is an elegant hall of mirrors instead of fire and scintillation.
What clarity do I need for an emerald cut?
Higher than for a round. The large open table reveals inclusions, so VS2 or better is the usual target to keep the stone eye-clean. Always check the clarity plot and images.
Does an emerald cut look bigger than a round?
Often yes for the same carat weight, because it retains weight efficiently and its elongated outline spreads across the finger. Its open look, though, means cut and clarity show clearly.
