Clear quartz sphere on metal stand :  A Master Hearler .
Origin : Brazil .
For centuries, since the time of the Celtic Druids, the crystal ball has been shrouded in a veil of occult energy and power. One of the most common visual associations with a Clear Quartz crystal ball today is the image of a psychic reader gazing into a crystal ball to foretell a person's future or access the past.
Here's what Judy Hall says about clear quartz:
From The Crystal Bible, "Quartz is the most powerful healing and energy amplifier on the planet because of its unique spiral crystalline form.  This crystal works at a vibrational level attuned to the specific energy requirements of the person needing healing or undertaking the spiritual work.  At a spiritual level, this crystal raises energy to the highest possible level."
