Inner diameter approximately 17cm.

The seven inclusions are as follows: Lepidocrocite: Dispelling negative thoughts Goethite: Creativity, confidence, and assistance Cacoxenite: Resolving worries and anxieties, spiritual growth Amethyst: Peace of mind and a loving heart Smoky Quartz: Dispelling negative energy and increasing positive energy Rutile Quartz: Intuition and connection to higher dimensions By the way, rather than which inclusions are present determining value, the "arrangement," "amount," and "transparency" seem to be more important. Super Seven, which you can choose to your liking, is a charming natural stone. All of our natural stones have been cleansed, and we offer anonymous shipping and free shipping.
