Mohawkite is a rare copper arsenate mineral that contains traces of cobalt, iron, silver and nickel, so be sensible when handling it, and to be on the safe side wash hands after use, and do not use when making gem essences by the direct method.
Don't be put off by this however as it is a fascinating mineral that is both grounding yet very expansive to the energy bodies. Mohawkite's beautiful rainbow colours that play across its surface arise from the oxidisation of the metals and can be polished off. This is a great mineral for off-planet communication and for connecting with a variety of planetary bodies within our Solar System. It is also a very useful aid for Inner Plane journeying.
