Extra Facets (EF)
Occasionally a cutter will find the need to remove an inclusion near the surface or to compensate for facets which do not meet correctly and he will add an "extra facet". Extra facets have no effect on clarity grades. This is subdivided in Two parts : 01) EFCR : Extra Facets on Crown, 02) EFPV : Extra Facets on Pavilion.
