TSAVORITE
Tsavorite is a green grossular variety of garnet coloured by vanadium. It was discovered in Tsavo Park between Kenya and Tanzania. It often occurs in highly-fractured nodules, making it difficult to have tsavorites of large dimensions.
Each gemstone brought to the laboratory is analysed and identified, and a report produced accordingly.
