Shungite is a black stone made from mainly carbon.  The carbon makes it unusually lighter then most other crystals and also gives it a metallic black colour. Shungite is a great purification crystal and also has healing and grounding properties.  It has been used to improve health and is still used in elixirs and potions today.   It can also be used to amplify psychic power and cloaks you from bad energy. Each polished tumblestone comes in an organza bag with a printed guide containing all the scientific and healing properties of the crystal.  An excellent gift or keep sake. The size and shape of the crystal you receive may differ slightly from the image shown. Each stone weighs approximately 5-10g. Organza bag provided may change in colour but will generally be either black, white or gold.
