Physical properties
Hardness of 5-6 on the Mohs scale, typically dark gray to black in color with a dull luster and highly porous, vesicular texture.
Formation & geological history
Formed from molten lava erupting from volcanoes that cools rapidly on the Earth's surface, trapping gas bubbles to create its signature porous texture.
Uses & applications
Widely used in jewelry making, specifically for essential oil diffuser bracelets, as well as in landscaping and barbecue grills.
Geological facts
Lava stone is one of the most abundant rock types on Earth and forms the majority of oceanic crust.
Field identification & locations
