In diamond terminology, what does EF stand for?

Explanation:
Extra Facet is what EF stands for. This label is used when a diamond has additional facets beyond the standard cut pattern, with those extra facets affecting how light travels inside the stone and how it sparkles. You’ll see EF in some grading notes or descriptions to indicate this modification to the facet structure. The other terms aren’t standard abbreviations for EF: etch channels isn’t a commonly used diamond term, eye-visible isn’t an EF-related label, and fancy cut refers to the overall shape/style rather than indicating extra facets.
