This is a beautiful Opal Aura Spirit Quartz Cluster with vibrant, sparkling crystals.  It has beautiful color and shine.  It is much more impressive than the pictures show.  Opal Aura Quartz is clear quartz that has been bonded together with platinum at a molecular level.  The molecules of the platinum adhere to the natural electric charge which surrounds the quartz crystal.  The process uses only electricity to deposit the platinum layers and very little heat is involved, so that the integrity of the crystal is maintained.
