Obsidian is the ultimate cleaner. It pulls anything "bad" out of stones, people (you and others), and your environment. It shields against negativity.  Since these are smaller spheres, they will need to be cleaned more frequently.
 
The spheres are a little larger than a dime and will fit nicely on the little acrylic stands in the stands category.  They are the perfect size for gridding.
 
The price is per sphere.
 
Available: 1 and 2.
