My raw obsidian crystal nugget pendant necklace has been carefully handcrafted in stainless steel satellite.About obsidian: - Obsidian is a highly protective stone said to absorb environmental pollution and shield you from negative energies. - It is connected to the root chakra and used to enhance grounding, truth and integrity. - It is known as volcanic glass because it forms from molten lava that cools before it has time to crystallise. - It often combines with white cristobalite to form snowflake obsidian.Crystals have inclusions, which appear naturally in gemstones. Sometimes they can be accidentally mistaken as cracks, but they're actually minerals that have been trapped within the crystal as it has grown. Inclusions are perfectly natural and make each individual crystal unique. They're part of the crystal's natural beauty and history.
