Flower/Fireworks Obsidian Rough Chunk! Big Diggins Agate approx 410 million years agoFireworks Obsidian also goes by the name of Flower Obsidian. It is a very rare form of natural volcanic glass Obsidian found in Mexico. It has a very high mineral content, which gives this material its gorgeous pattern and colors! It often has chrysanthemum like flowering with a black or pink backdrop.
