Crazy Horse is not a birthstone but is affiliated with the zodiac sign Cancer. Calcites like Crazy Horse stone are belief to aid memory and increase the strength of habits. It has no particular chakras but its worldwide distribution is considered to be a function of its universalism; it clears all the chakras, raises overall body awareness and helps connect people and energy beings into a united network. One of the calcite’s most fascinating properties is that it emits electrical impulses when placed under pressure. Otherwise, this highly common mineral is considered rather ordinary. It is the most common mineral in stalactites (which hang from the ceilings of caves) and stalagmites (which form on the floors of caves).
Crazy Horse stone's blend of colors and patterns are due to the presence of aragonite and other trace minerals. Interestingly, calcite and aragonite are an odd set of almost-twin materials: they have the same chemical composition, but differ significantly in crystal structure. No 2 pieces are alike.
