Black Obsidian Oval Thumbstone 40mm

A plain black oval about 40mm across, polished to a mirror finish with a shallow dish for your thumb. Black Obsidian is volcanic glass, cooled too fast to grow crystals, and it has a directness to match. It grounds you quickly when your head is somewhere else entirely, and it keeps other people's negativity off you, which makes it the one to carry through a difficult day at work. Black Obsidian holds your focus where you set it, feeds your creativity, and pushes you to manifest a plan rather than keep turning it over. The small wooden cube in the photo is 1cm across and is there to show scale, and is not included.
