Comment: Pushy yellow sapphire with a fine hand-cut earning a rare 'excellent,' usually reserved for precision-cuts. Add 'free of inclusions', no window and untreated to get a high-end all-natural round sapphire scaring any mundane diamond. Camera overload from too much luster. See side- and backimage for best color judgment and great cutting. Fresh lab report can be done and will show origin 'Ceylon' if possible. Intense yellow with equally bright green as secondary hue, typical for unheated yellow sapphire from Sri Lanka. Over 6mm round for e-rings over 4 and up to 6 with prongs, 7 with bezel. Will not darken in bezel. Never pale, never dark, always shiny yellow without flowery mildness but energetic sparkle.
