Ruby zoisite is a relatively rare type of stone from Northern Tanzania.
It's believed to have formed during the geological time period known as the Neoproterozoic era.
Due to the difference in hardness of the minerals zoisite and corundum it can be a difficult material to cut.
Ruby zoisite is also known as ruby in zoisite and anyolite.
The name 'anyolite' comes from the Maasai word for 'green'
The Maasai tribe work some of the smaller ruby zoisite mines in the Arusha region of northern Tanzania.
