Mahogany Obsidian is a naturally occurring volcanic glass created when felsic lava rapidly cools with minimal crystal growth. Obsidian is black or dark green, and the mahogany comes from a section of magnetite or hematite are trapped in the glass.

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. See more about caring for Semi Precious Stone here

Natural Stone 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.
