💫 Did you know?
“Apache Tear” is a traditional form name rather than a separate mineral species. Not every piece of black obsidian qualifies: the name usually refers specifically to rounded obsidian nodules associated with perlite and displaying warm brown translucence in thin areas.
Obsidian measures approximately 5–5.5 on the Mohs scale and can form extremely sharp edges when chipped. Clean sound pieces briefly with lukewarm water, mild soap and a soft cloth, and protect them from impact, steam, ultrasonic cleaning and rapid temperature changes.
