When volcanoes erupt and lava hardens too quickly to develop a crystalline structure, obsidian is formed. Called nature’s glass or volcano glass, it has been used throughout the ages as arrowheads, spear points, and knives. Even today, it is the basis of the best surgical steel. Silver sheen obsidian is black or deep brown obsidian with an iridescent silver sheen caused by gas bubbles that have aligned across the layers. It is called the talisman of those who dare to see or the mirror stone. The Olmecs made concave mirrors from it to start their fires, while the Maya and Aztecs wore them to show their status and to divine a person’s destiny.
Silver sheen obsidian helps one see how others see them. It improves perception, sharpens the senses and intellect, and brings general advantages to all who wear it.
