This is a power piece if ever there was one! It's a visually striking piece, with the black and white colors, and variety of materials. And the gemstones are incredible. Quartz (the master healer) amplifies the energies of other stones. Obsidian is a powerfully protective crystal, forming a shield to protect the wearer from negativity. Tourmalinated quartz is quartz with black tourmaline needles (you can best see these in the dangles), so it has the qualities of quartz and tourmaline. It is a powerful shield stone that, depending on the intent of the wearer, can return the negative energy (like a mirror) or transform it into positive.
