African fine color change alexandrite

An unusual combination of a fine color change, exceptional clarity, and excellent cutting make this stone is one of the very top alexandrites ever to be unearthed from this deposit in Tunduru.

The Tunduru area in southern Tanzania, near the Mozambique border produced a large quantity of sapphires, spinels and chrysoberyls in 1993. All of the easily accessible areas were mined out in one year. Today, mechanized mining is still producing limited quantities of material, but work is difficult in such a remote area. The Tunduru region has produced a variety of outstanding stones including a large clean top color 40ct+ rough diamond and some stunning alexandrite and vanadium colored chrysoberyls
