Mahogany Obsidian

Mohs hardness of 5 to 5.5, dark brown and black coloration with flame-like patches, vitreous luster, amorphous crystal structure with conchoidal fracture.

Formed from rapidly cooling felsic lava extruded from volcanoes, lacking sufficient time for crystal growth.

Used primarily for ornamental carvings, polished tumbling stones, jewelry making, and metaphysical collection.

Mahogany obsidian derives its unique reddish-brown color streaks from the presence of iron oxide inclusions trapped during rapid cooling.

Identified by its glossy vitreous luster, sharp conchoidal fracture edges, and distinctive black and brown mottled patterns. Commonly sourced from regions with recent volcanic activity like the western United States, Mexico, and obsidian flows globally.
