Chalcedony is a stone of breakthrough power. A stone for the shy. It improves self-expression, the balance between mind, speech and body (intentions, communication, health) and the transformation of "weaknesses" into strengths. The whole thing is enhanced by the energy of a hand-made spiral, which accelerates the flow of energy and emanates the color and vibration of solar power. This spiral also protects the owner against the influx of unwanted energies from the outside.
