Abstract

Aquamarine is a kind of gemstone having attractive color, valuable and being a
potential material in gemological industry. In Vietnam, Thach Khoan area has become a noticeable
location to explore aquamarine. However, the researches of aquamarine are still limited.
Therefore, this study was conducted to determine the characteristics of aquamarine. Eight
aquamarine samples from granitic pegmatites in Thach Khoan commune, Thanh Son District, Phu
Tho Province were investigated by classical gemological methods, Electron Probe Micro-analysis
(EMPA) and Laser Ablation – Inductively Coupled Plasma – Mass Spectrometry (LA-ICP-MS)
methods, Raman and Fourier transform infrared (FTIR) spectroscopy. Results showed that
aquamarine presents a low concentration of alkali and high amount of iron. Raman and IR
spectroscopy indicate the vibrations of specific bonds including Si-O, Al-O, Be-O, the presence of
CO2 and type I H2O in structural channels. By dint of that, we are going to study the potential
treatment methods of aquamarine in Vietnam in the following study to enhance its quality as well
as value in the global market.
