Description
The Obsidian Black Rock – Pack of 10 Geological Specimens is an eye-catching collection of volcanic glass, perfect for geology students, educators, and collectors. Formed from the rapid cooling of lava, obsidian is an igneous rock prized for its deep black, glassy appearance and smooth, conchoidal fracture.
Each specimen is an ideal size for classroom study, lab work, or hands-on exploration. These rocks provide an excellent way to observe unique volcanic textures, luster, and formation processes up close. Their dramatic colour and glossy finish also make them a striking addition to any geological collection or display.
This pack of 10 specimens ensures you have plenty for group activities, demonstrations, or individual learning. Designed for educational and laboratory use, it provides students with a tangible connection to Earth’s igneous activity and natural history.
