Ruby zoisite (anyolite) and ruby in a tertiary orthorhombic rhombohedral zoisite matrix. Lithotherapy books say that zoisite is a dynamic stone that brings out buried feelings and boosts sexual potency. Deacidifies, regenerates, stimulates fertility, spleen, prostate, testes and ovaries. It is found in Madagascar, Austria, Russia, Cambodia, Kenya. Very often we find the presence of ruby hence its trade name ruby zoisite, but we also find it lavender blue when it has been subjected to heat, for example during a volcanic eruption, this blue zoisite is called Tanzanite.
