Quartz spheres have multiple uses. As a meditation tool when held in both hands help us focus on our practice. The energies of such a sphere smooth the edges of our aura and offer protection and balance of our light. In a healing session if we place such a sphere at the crown or base/earth star chakras, the whole aura re-callibrates itself into the same shape. This has the effect of encouraging the aura to become balanced and harmonised. This clear quartz sphere measures 3.75'
