    • Abstract
  • The study represents the gemmological characteristics of "Tairus" hydrothermal beryls,which were procured by the Tairus Co.Ltd.The results show that the standard gemmological characteristics,such as RI and SG,overlap with those of the natural counterparts.Microscopic features,such as "chevron" growth could readily identify the materials as synthetic which is visible even with unaided eyes.However,there might be cases when the internal features may not identify the material that the FTIR and EDXRF analysis could be needed to conclude the stones as synthetic.
