Butterfly Jasper is a stone that is mined in Mexico. It is called butterfly or sometimes butterfly wing because the patterning of the stone resembles that of butterfly wings. It is a brecciated jasper, which means that as it was forming it broke up into a series of fragments which then healed together producing an abstract pattern.
Jaspers are said to promote stability, comfort, strength, and security. Butterfly Jasper has an additional element in a metaphysical sense. Butterfly jasper is said to make the soul feel free and light, and lets the imagination soar to new heights.
