Black obsidian is a natural glass that forms when intensely hot; molten lava is quickly cooled and hardened into a non-crystalline glass. There is a lot of fake, man-made glass on the market sold as obsidian which is hard to differentiate from the real thing. It is important to buy obsidian from trusted sources. Obsidian is one of the zodiac stones for Capricorn.
Like glass, obsidian breaks apart easily and can be sharpened. Many ancient tribes and civilisations would fashion obsidian into weapons, spearheads, and arrowheads.
Obsidian is a potent stone that can be overwhelming for some due to its ability to bring forth negative emotions to be released. It has a strong, protective quality that is said to quickly and efficiently remove negative energy both from oneself and their environment.
