Aventurine Tumblestones
In industry,Mica has insulating ans shielding properties that protect whatever is surrounded by it. It has long been used to protect and insulate pottery from too much heat in the kiln.
These same effects are what give Aventurines their generic healing properties, as this shielding and insulating quality is enhanced by the Quartz within the stones. This means that Aventurines are incredible crystals of protection on all levels of our being.
