When you want to cover all your chakras with the ease of one stone. This stone has you covered root to crown!
 
What is a worry stone? A small oval stone, smooth on both sides and includes a thumb indentation on one side. The purpose of the thumbprint is to allow you to rub your thumb back in forth as a way to calm the mind.
 
I selected this stone for the ease of using anywhere, during meditation, at your desk, while flying-anywhere.
