Ways to identify polished Black Tourmaline vs Obsidian

When distinguishing between polished black tourmaline and polished obsidian, you can look for these characteristics:

• Texture: Polished black tourmaline often has a rougher texture compared to polished obsidian, which is very smooth and glassy.
• Transparency: Black tourmaline is opaque with no light passing through, whereas obsidian may show translucency at its thin edges.
• Luster: Obsidian typically has a shiny, vitreous luster, much like glass. Black tourmaline’s luster is more subdued, resembling that of polished wood.
• Formation: Obsidian is volcanic glass that forms from rapidly cooled lava, contributing to its smoothness. Black tourmaline is a silicate mineral that forms in a different process, often in or around other minerals.

These tips should help you tell them apart. Remember, the most important aspect of working with crystals is to choose the one you feel a connection with, as both have their own unique beauty and properties. Enjoy exploring these captivating stones!
