Perfect for crystal grids/layouts.
Ideal to carry with you.
These are man made blue obsidian tumbles. While blue obsidian DOES exist in nature it’s not of this colour or size.
Obsidian by nature is volcanic glass and is formed during eruptions. Man made obsidian is also a form of glass.
Now you either work with man made pieces or you don’t. I do and have several dragon skulls in various shades of blue and home found them to be very clear channels.
Go with your gut.
You get all 3 tumbles shown. Each are 2.5cm in size
