These Obsidian slabs are natural obsidian in primarily solid black coloring, but can have slight color variations or patterns, mostly leaning towards Mahogany Obsidian with streaks and patterns of reddish brown, or occasionally have effects like "Rainbow Obsidian" or "Midnight Lace Obsidian." 

Price is for 1 lb lot. Shapes, sizes, and colors will vary between each slab. Most slabs between 1" - 3" long.
