Tourmaline in Quartz combines the properties of Tourmaline and Quartz Crystal. Tourmaline purifies ones own energies and protects from negativity, while Quartz amplifies energies focused through it. This combination makes Tourmaline Quartz a powerful shield-stone that, depending on the desired intent of the wearer, can amplify and return negative energy, like a mirror spell, or can convert the negative energy into positive energy for the wearer.
