A smooth mahogany obsidian oval (16x13mm) is wrapped securely on 20-gauge sterling silver wire. The ring starts at size 8 and can be gently adjusted for fit—though we recommend setting it once to preserve the wire’s integrity.

Mahogany obsidian’s deep reddish-brown streaks, formed from natural iron inclusions, evoke the raw beauty of volcanic glass. In crystal traditions, it’s associated with grounding and strength.
