|Ruby-Zoisite, also known as anyolite, is the natural combination of ruby and zoisite crystals in a single specimen. Zoisite, the same mineral as tanzanite, provides an earthy green color while ruby lends pink and red highlights. Ruby-zoisite is usually shaped as cabochons or carved into decorative objects.
Ruby-Zoisite was first discovered in 1954 in Tanzania. The name anyolite derives from the word for "green" in the native language of the Masai tribe.
Ruby-Zoisite has a hardness of 6.5 to 7 on the Mohs scale, and is thus of moderate hardness.
