Aquamarine Gemstone

Authors(2) :-Nazia Sultana, Sankara Pitchaiah Podila

Aquamarine gemstone is one of the Beryl mineral varieties with Beryllium aluminium silicate composition. Its bluish green color caused from Fe2+ions puts it as a special variety. It is used in jewellery and has some industrial applications. This beautiful gemstone is reported from few countries only, namely India, Brazil, Canada, China, Italy, Pakistan, Russia, Ethiopia, Madagascar, Mozambique, Namibia, Nigeria, United Kingdom, United States, Mexico and Vietnam. The present study collected its occurrences from various parts of the world and studied the variation of oxides analyzed from Aquamarine. It is observed that SiO2 ranges from 64.99% to 72.48%, Al2O3:11.63% to 19.91%; BeO: 12.9% to 13.79%; FeO: 0.11% to 5.03%; CaO:0.01 %to 0.83%;MgO:0.00% to 1.93%; Na2O:0.10% to 3.53%; K2O:nearly zero to 3.31% and MnO:0.00% to 0.06%.
