About TsavoriteHide

Formula:
Ca3Al2(SiO4)3
Name:
Named proposed by Tiffany and Co. president Sir Henry Platt after the Tsavo East National Park, Kenya, which lies near where tsavorite was originally found.
It was first discovered by the Scottish-born Kenyan gemologist Campbell R. Bridges (1937 – 11 August 2009), in Lemshuko, 15 km away from Komolo, in north-east Tanzania.
A variety of Grossular

A green chromian, vanadian Grossular.

5 chemical types were recognized for the Neoproterozoic Metamorphic Mozambique Belt material:
- vanadian grossular, V>Cr>Mn
- vanadian grossular, V>Mn>Cr
- Mn-bearing vanadian grossular, Mn>V>Cr
- Mn-bearing chromian grossular, Mn>Cr>V
- Cr- and Mn-bearing grossular, Cr>Mn>V
The types differ in terms of their UV-VIS-IR spectra. Fe2+-Ti4+ charge transfer is possible. Trace OH groups may be present.
