Mineral Information:

Synthetic obsidian is man-made glass designed to imitate the appearance and properties of natural obsidian, a volcanic glass formed when lava cools rapidly. While it may look similar—often glossy and dark—synthetic obsidian is not formed through geological processes and lacks the natural mineral composition and historical context of real obsidian.

What Is Obsidian?

• Natural Obsidian: Volcanic glass formed when felsic lava cools so quickly that crystals don’t have time to form.

• Composition: Primarily silicon dioxide (SiO₂), with trace minerals and gas bubbles that give it natural sheen and color variations.

• Common Colors: Black, mahogany, snowflake (black with white inclusions), rainbow sheen, and greenish tints (rare).

What Is Synthetic Obsidian?

• Also called: Man-made obsidian, glass simulant, or fused silica glass.

• Composition: Artificially melted silica-based glass, often mixed with dyes or metallic oxides for color effects.

• Appearance: Shiny and smooth, often sold in colors like bright green, aqua blue, pink, or even with “moss-like” or glittery inclusions.

• Common in: Jewelry, tumbled stones, crystal shops (sometimes labeled misleadingly).
