Emerald – Natural, Faceted, Green, 34.62 ct

This 34.62-ct emerald received a GIA clarity grade of SI1-2 (small inclusions). For a Type III gem, like an emerald, this grade means inclusions are "prominent" to "very prominent" to the unaided eye. In contrast, for a Type I gem, like fellow-berylsaquamarine, morganite, and heliodor, this grade would mean inclusions are "slightly" to "easily visible" to the unaided eye.
