Aura quartz is a natural Quartz crystal that has been processed with platinum and magnesium fumes in a high-pressure vacuum chamber. The platinum and magnesium gives the natural crystal its new colour. The colour is not a coating, but rather a new layer of precious platinum/quartz atoms that are both natural elements, but mixed in a way that enhances the energy of the quartz with the colour energy of the violet ray of colour.
Violet Aura Quartz, in terms of healing properties, is based off of its colour energy, violet. Clear Quartz is an amplifier, so it will amplify the healing properties provided by the colour energy. Violet brings spiritual wholeness and instils happiness. It is also the colour of creativity, intuition, and clear sight. This can be used as a creative aid or a meditation aid.
