AAA-Grade Ruby Zoisite Stones
These really are the finest-grade ruby zoisite tumbled stones. Classed as AAA-grade, they boast an exemplary polish along with rich colour and distinctive markings.
Not all stones feature inclusions of red corundum, but unfortunately, when ruby zoisite is tumbled, that's just how it is.
The corundum in ruby zoisite is Longido ruby, which is relatively rare and can only be found in the Arusha region of Northern Tanzania.
Ruby zoisite is a combination of green zoisite and red corundum.
We also have grade-A ruby zoisite tumbled stones and grade B, plus a small collection of rough Longido rubies.
These are medium-sized tumbled stones, but as with all tumbled stones, size varies slightly from piece to piece.
