Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It has a glossy black finish that is both striking and mysterious. It is created when lava is cooled so quickly that its minerals do not have enough time to crystallize. This makes for a rock that is incredibly hard and smooth with a glassy texture. Obsidian is said to be a powerful protection stone, shielding its wearer from negative energies and aiding in spiritual grounding. It is also believed to bring clarity and insight, helping to remove emotional blockages and promote inner growth. With its strength and beauty, obsidian is the perfect crystal for those looking to find strength and balance in their lives.
