Polymer-Filled Aquamarine

open access: yesGems & Gemology, 2009
The authors have encountered hundreds of polymer-filled aquamarines in the Chinese jewelry market. This treatment can be identified with a standard gemological microscope, since it has characteristics such as a flash effect and relief lines. In addition, some of the filled fractures fluoresce chalky white to long-wave UV radiation.
