What is the Rarest Color of Garnet?
The rarest color of garnet is blue. Unlike the more common red garnets, blue garnets are extremely scarce and highly sought after by collectors and gem enthusiasts. This unique hue is due to the presence of vanadium, which causes the stone to change color under different lighting conditions.
