Raw Obsidian, Igneous Rock Specimen - Hand Sample, ± 2.75"

• OBSIDIAN | Obsidian, also known as volcanic glass, forms from lava that cools almost immediately upon eruption, usually into water
• GREAT FOR GEOLOGY CLASSROOMS | Obsidian shares many physical properties with its major chemical component, quartz, despite looking dissimilar - great for classification exercises
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• INDIVIDUALLY PACKAGED & LABELED | Each specimen sample is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Obsidian Specimen
Single Sample, 3"

Obsidian, also known as volcanic glass, forms from lava that cools almost immediately upon eruption, usually into water. Excellent for classroom mineral study and identification. Obsidian shares many physical properties with its major chemical component, quartz, despite looking dissimilar - great for classification exercises.
While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, labeled & barcoded for easy identification and storage.

Selected & Processed by a Geologist.
