Comment: Intense deep hue balanced between green and blue, at times more blue (dark light settings), at times more green (full light). Rich dense crystal. Beautifully designed with strong bright luster running smoothly through the stones in motion. Precision cutting, good polish. No visible inclusions, no window, no treatments, the rare 3NOs quality. 10x6mm will allow for a pendant or a large ring over size 7. White gold or platinum suits best IMO. In a ring, the sharp corners should be protected in a setting or they will abrase easily over time. Old Afghani quality not much seen anymore.
