Red-hot burning orange lava flows, cooling to form a deep black crust, still glowing, and showing off the formation of earth itself. Lava is magical, both creating and destroying, forming a wide array of rocks from the floating pumice to the deep black, glass-like obsidian. Obsidian is a new addition to our color-shifting multichrome nail polish line. Obsidian features a deep black hue that shifts to molten shades of umber, crimson, orange, and gold. Obsidian covers well in 2-3 coats.
