Tumble Stone - Obsidian Black

Obsidian is formed after an immediate solidification of very hot magma, i.e. lava. It is the only natural glass found in nature. In its chemical composition, we can distinguish many minerals that make obsidian black, brown-green, dark red or snow-coloured. 

According to beliefs, obsidian is an ideal stone for delicate, spiritual and sensitive people. Its task is to effectively protect against bad energy, both the energy that comes from within us (i.e. negative thinking) and the external energy.
