This cute Snowflake Obsidian donut shaped crystal hangs beautifully around the neck. Snowflake Obsidian helps you recognise and release "wrong thinking" and alleviate stress. Iron and other transition elements may give the obsidian a dark brown to black colour. The snowflake element comes from radially clustered crystals of cristobalite that are captured in the glass. The black braided rope necklace has a lobster clasp and approximately 60cm long. The pendant itself varies approx 2-3cm in size. Sizes and shape of the crystal will vary from the picture shown as each pendant is unique.
