A Colombian emerald weighing 1.68 carats, GIA-confirmed origin — the stronger of the two labs, and worth noting on a stone this size. Bright green with the same lively, saturated color as the rest of this parcel. Elongated octagonal step cut. It reads clean to the eye in hand, with the fine, natural inclusions typical of genuine emerald rather than anything that disrupts the face-up look. GIA grades the clarity enhancement as F1 — minor, the lightest classification on their scale. A substantial, bright Colombian emerald with the most authoritative documentation in the group.
