Snowflake Obsidian is Black Obsidian with small white inclusions of the mineral Cristobalite, giving the stone the spotted white effect on the glassy black stone surface.  Cristobalite, like Black Obsidian, is formed at very high temperatures during volcanic activity.  Cristobalite has the same material components as quartz, but a different chemical structure making it a completely different mineral.

Black Obsidian is a naturally occurring volcanic glass that has been used by prehistoric man by fashioning into tools, primarily weapons.  The association with Black Obsidian as a protective weapon is more than symbolic if you can make the connection with your stone as part of your energetic defence toolkit.  Black Obsidian is a highly energetic stone, yet grounding, being associated with your root chakra.  Black Obsidian can provide comfort in times of high stress and allow you to see things more clearly.

Snowflake Obsidian, like Black Obsidian, is one of the most protective stones available, being particularly effective in dispelling and dissipating negativity and unwanted energetic fields.  Snowflake Obsidian adds an extra dimension to these properties with the Cristobalite component, to create a stone that also works with your third eye chakra as well as your root chakra.  Deep meditative practice with Snowflake Obsidian can assist your connection with spirit or angelic guides and can also assist in past life recall. 

Snowflake Obsidian is relatively uncommon in comparison to Black Obsidian, and is not often seen in large carved pieces.  Brown Snowflake Obsidian is less common again, where the Black Obsidian has been coloured brown due to impurities and inclusion content.

Stone carved into the human skull form is a tool that can be used with meditative practice to expand your consciousness.
