Sizing: The crystal chips often have one side that is at least 5 mm in one dimension. Crystal chip bracelets are small pieces of crystal that have been tumbled until smooth, and then strung together on elastic. The malachite chips can vary sometimes in their shape and can be a little more varied in shape than some other crystals such as say amethyst. The wonderful green of malachite comes through as even does some of the patterning within the crystal. Country of Origin: Zaire
