Pele is the Hawaiian goddess of volcanoes and fire and the creator of the islands of Hawaii , which are all volcanic in origin. The blood of Pele refers to any red colouration in the usually black Obsidian rock.
Obsidian is also called Volcanic Glass, due to its extremely smooth appearance .
Obsidian is formed as a result of the extremely rapid cooking of lavas extruded during volcanic eruptions. The rapid cooling does not allow any crystal formation . Much Obsidian is black , but if it contains some mineral impurities such as iron or magnesium , a mixed colouration may result , as in the deep reds and browns in Mahogany Obsidian .
Obsidian was used by many ancient peoples to make arrow heads and knives , as it can be fashioned to create extremely sharp edges.
Said to assist in decision making and stabilizes the mind.
