I. The Metaphysical Reading
How the stone has been held.
Mahogany obsidian is held as a stone of grounded strength, boundary, and quiet protection. Its warm brown veins are said to soften obsidian's sharp reflective edge, offering support rather than confrontation.

II. The Scientific Reading
What the lattice actually does.
Mahogany obsidian is a naturally occurring volcanic glass formed from rapidly cooled, felsic lava. Its characteristic mahogany-brown banding is produced by finely disseminated hematite and magnetite inclusions within an otherwise black obsidian matrix.
