Synthetic Rubies and synthetic Colored Sapphires before and after Beryllium treatment. Dominant trace elements are in bold.
Note: Only Cr-rich samples were reacting to the Beryllium treatment. Be = Beryllium, Na = Sodium, Mg = Magnesium, Si = Silica, K= Potassium, Ti = Titanium, Cr = Chromium, Fe = Iron, Ni = Nickel.
