Obsidian rock, a natural volcanic glass, offers a unique and striking addition to any landscape design, and at rockscapes.net, we’re here to guide you in discovering its beauty and versatility. This comprehensive guide explores where you can find obsidian, its characteristics, and how to incorporate it into your rockscapes, ensuring you create a stunning and sustainable outdoor space. Rockscape designs, garden stones, and landscaping rocks can enhance the beauty.
1. What Is Obsidian Rock?
Obsidian is a naturally occurring volcanic glass formed when felsic lava cools rapidly with minimal crystal growth.
1.1 Formation and Composition
Obsidian forms from quickly cooled lava, typically rhyolitic in composition, meaning it’s rich in silica (65 to 80 percent) and low in water content. The rapid cooling prevents the formation of crystal structures, resulting in its glassy texture. According to research from Arizona State University’s School of Earth and Space Exploration, the viscosity of the lava plays a crucial role; high viscosity impedes crystallization, solidifying the lava as glass.
1.2 Physical Properties
Obsidian is known for its smooth, uniform texture and conchoidal fracture, meaning it breaks with smooth, curved surfaces. It typically has a glassy luster and a hardness slightly greater than window glass. Its color is usually jet-black, but the presence of hematite (iron oxide) can create red and brown varieties. The inclusion of tiny gas bubbles can also produce a golden sheen, and dark bands or mottling in gray, green, or yellow may also be present.
1.3 Types of Obsidian
- Black Obsidian: The most common type, known for its pure black color and glassy texture.
- Snowflake Obsidian: Contains white, snowflake-like inclusions of cristobalite, a form of silica.
- Rainbow Obsidian: Displays iridescent colors due to microscopic layers of magnetite nanoparticles.
- Mahogany Obsidian: Features reddish-brown bands or mottling due to the presence of iron oxides.
- Gold Sheen Obsidian: Contains tiny gas bubbles that create a golden sheen when light reflects off them.
- Silver Sheen Obsidian: Similar to gold sheen, but with a silver reflection.
2. Where Can You Find Obsidian Rock?
Obsidian is typically found in regions with a history of volcanic activity.
2.1 United States
The United States is home to several significant obsidian deposits, particularly in the western states.
2.1.1 Yellowstone National Park, Wyoming

2.1.2 Glass Buttes, Oregon
Glass Buttes in Oregon is another prominent location for obsidian. This area is known for its diverse range of obsidian types, including rainbow, gold sheen, and silver sheen obsidian.
2.1.3 Newberry National Volcanic Monument, Oregon
Also located in Oregon, this monument features extensive obsidian flows, including the Big Obsidian Flow, which is one of the youngest lava flows in the state.
2.1.4 California
California has several obsidian sources, including:
- Mono Craters: This area contains numerous obsidian domes and flows.
- Clear Lake Volcanic Field: Known for its high-quality black obsidian.
2.1.5 Arizona
While Arizona is more famous for other types of rocks and minerals, obsidian can be found in some volcanic areas, such as near Superior.
2.2 Iceland
Iceland, with its active volcanoes, is a prime location for obsidian. Mount Hekla is a well-known source of obsidian in Iceland. The island’s unique geological activity continually produces new obsidian deposits.
2.3 Italy
The Eolie Islands off the coast of Italy are another significant source of obsidian. These volcanic islands have a long history of obsidian formation, and the rock was used by ancient civilizations for various purposes.
2.4 Other Global Locations

3. How to Identify Obsidian Rock
Identifying obsidian involves recognizing its unique characteristics.
3.1 Visual Inspection
Obsidian typically has a glassy appearance and is often black, though it can also be brown, red, or green. Look for a smooth, shiny surface and a conchoidal fracture pattern when broken.
3.2 Hardness Test
Obsidian has a hardness of around 5.5 on the Mohs scale, meaning it can scratch glass but can be scratched by steel.
3.3 Streak Test
Obsidian does not produce a streak, as it is a glass. This can help differentiate it from other black rocks that may leave a streak when rubbed against a streak plate.
3.4 Density Test
Obsidian has a relatively low density compared to other rocks. Its density usually ranges from 2.35 to 2.60 g/cm³.
