Core features

Mahogany Obsidian: Volcanic glass

Cold air is like a shock to red-hot Lava—instead of slowly crystallizing, it instantly transforms into volcanic glass. With its palette of fiery red and ash black, this Obsidian still reminds us today of its fiery origins and is guaranteed to turn heads.
