Obsidian is a naturally occurring volcanic glass created when felsic lava rapidly cools with minimal crystal growth. Obsidian is black or dark green; one may also find sections of Gold Obsidian or Silver Obsidian, which is when microscopic pockets of air become trapped during the cooling process.
Natural Stone Manufacturer's Disclaimer: Please note when ordering a set of our Semi-Precious Dice, they are created from natural materials, and there will be differences between every die. Our Semi-Precious Dice are hand-crafted, so there may be minor variations such as slight size differences, asymmetrical faces, or off-centre numbering. As such, each die is unique and may not be perfectly symmetrical; their roll is as balanced as one would expect from acrylic dice.
