Multicoloured Stones

Multicoloured Stones Stones which consist of various colours, such as bloodstone (green and red), tourmaline (many combinations) and the opal (all colours) are, obviously, more complex in their magickal make-up than single hued stones. For most of these, simply look at the colours individually and determine the stone's uses by combining the energies of each. Opals are a special case, as are all stones which exhibit rainbows or a variety of colours. [Encyclopedia of Crystal, Gem, and Metal Magic-Scott Cunningham]
