Ruby in zoisite, or anyolite, is a metamorphic rock that forms at very high pressures and temperatures. Zoisite is a green form of a mineral class that includes tanzanite and thulite. Ruby is the magenta red variety of the mineral corundum, the second hardest mineral, next to diamond. Ruby zoisite combines the heart chakra (green) with the root chakra (red) to tie the mind and body. This stone helps the mind resolve what the heart desires, allowing one to pursue their dream within reality.
