Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava from a volcano cools rapidly with minimal crystal growth. Obsidian is typically black in color, but it can also appear in shades of brown, red, or green due to impurities. It is known for its sharp edges and smooth, glassy texture, making it a popular material for tools, weapons, and decorative objects. **

Without being able to physically examine the object in question, it is difficult to determine if it is real obsidian. However, there are a few ways to test for authenticity, such as checking for conchoidal fractures, observing its color and transparency, and conducting a scratch test. It is best to consult with a professional or use a testing kit to confirm if the object is indeed made of real obsidian. **
