It has been reported that large quantities of filled aquamarine (bead, carving, cabochon) have entered the Chinese market. The experts claim the treatments can be identified with 10x and microscope. Gem ID tips: Look out for flash effects and relief lines. Filled fractures may fluoresce chalky white under long-wave UV radiation. Many believe the treatment could easily be used in faceted aquamarines. It's just a matter of time. If doubtful always consult a reputed gem testing laboratory.
