Emerald cut

JewelryWiki Editorial·2 sources·Reviewed 2026-08-04

A step cut, not a brilliant. Concentric trapezoidal facets produce a hall of mirrors rather than sparkle — and show inclusions far more readily.

Properties

Cut styleStep [1]
Receives a GIA cut gradeNo [1]
GIA issues cut grades only for the standard round brilliant; all other shapes are fancy shapes and receive none.
Typical facet count58 — 25 on the crown, 32 on the pavilion, and the culet [2]
Trade source. Fancy-shape facet counts are not standardised and published figures differ.
Optical characterStep cut: broad flashes from concentric trapezoidal facets, rather than the scintillation of a brilliant. [1]
What to watch forIts open table hides nothing. Buy a higher clarity grade here than in a brilliant cut — inclusions that disappear in a round are plainly visible in an emerald. [1]
