Physical Properties of Elbaite
Vitreous, Resinous
Transparency:
Transparent, Translucent
Colour:
Green, blue-green, blue, red to pink, orange, yellow, colourless
Comment:
The isomorphous substitution of ions forms the different colors of tourmalines. The cations in the structure (such as Fe, Mn, Cr, etc.) exist in a wide range of isomorphous substitutions, which gives tourmaline a very rich color. There are no or very few transition metal ions in colorless tourmaline.
The red hue of tourmaline is attributed to the d-d transition of octahedral Mn3+, Mn2+, or Mn2+-Mn3+ intervalence charge transfer (IVCT) in its crystal structure. The deep blue color is due to Fe2+, Fe3+, and Mn3+. The βneonβ blue color of ParaΓba tourmaline is attributed to Cu2+ and Mn3+. The yellow color could be associated with both the Fe2+-Ti4+ and Fe2+-Fe3+ intervalence charge transfers. Regarding the color genesis of green tourmalines, many previous experimental studies have shown that it is due to the isomorphous substitution of transition metal ions, such as Cr, V, and Fe, at the Y or Z position in its structure. It has also been shown that the green color of tourmaline is due to defects in the crystal structure of tourmaline.[[1]]
The chromogenic components iron and manganese were found in the green elbaites; however, the bivariate correlation analysis indicated that the Mn content had no impact on the color, whereas the Fe content significantly affected both the lightness and the hue of green elbaites. The primary factors influencing the color of tourmaline were the absorption band at 720 nm caused by the Fe2+ d-d transitions and the 300 to 400 nm wide absorption edge extending to the visible range due to the O2β-Fe3+ charge transfer. Infrared spectroscopy indicated that the color of tourmalines was also influenced by their structure. As the degree of Y and Z octahedral distortion in the tourmaline lattice increased, the lightness of the tourmaline decreased and its color deepened.[[1]]
