Welcome! Rainbow Quartz is quartz crystals that exhibit a natural rainbow effect within them. This phenomenon is caused by light reflecting off internal fractures, inclusions, or water bubbles inside the crystal. The effect creates beautiful, multicolored flashes that resemble a rainbow. Distinction from Other Quartz Types: • Unlike Phantom Quartz, which has layered inclusions resembling shapes or ghosts, Rainbow Quartz is prized for its optical light effects, not for internal mineral formations. • It can occur naturally or be enhanced by heat or polishing to highlight the rainbow patterns. Rainbow Quartz is a favorite in crystal healing and decoration for its unique and vibrant aesthetic.
