| The Badger Flats area is also well known for clinozoisite, garnet, hematite, scheelite, vesuvianite, wollastonite, and zoisite. |
| Some say that tanzanite, the blue variety of zoisite, is what set off the gem rush in East Africa, although Madagascar was producing other fine gems at the time. |
| The gem that put Tanzania on the world precious stone map was its namesake tanzanite, a blue zoisite found solely near the town of Arusha in northern Tanzania. |
| It forms a series with clinozoisite and, together with a group of other minerals including zoisite, the allanites, and piemontite, is a dominant member of the epidote group. |
| Tanzanite is a gemstone that's a variety of blue or purple colors of the mineral zoisite. |
| The mineral readily weathers to other aluminous minerals e.g., margarite, zoisite, sillimanite, and kyanite. |
