Comment: A unusual fresh and squeaky cornflower blue makes this lovely stone a treat for the color enthusiast. Very moderately priced due to some missing depth, which is easily balanced out by a face that makes up for a 4 carat stone. Best set in a closed bezel. Lucid crystal and exceptionally clean.
