Description
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.
We recommend that you do not roll your semi-precious stone dice on a surface harder than they are (i.e., glass or wood tables). We suggest you roll them in a dice tray to prevent possible chipping or breaking.

Natural Stone Disclaimer: Please note when ordering a set of Level Up's Semi-Precious Dice, they are created from natural materials, and there will be differences between every die. Level Up's Semi-Precious Dice are hand-crafted, so there may be minor variations such as slight size differences, asymmetrical faces, or off-center 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.
