怎么看是玛瑙还是玻璃

　　A: It is difficult to tell the difference between malachite and glass just by looking at them. However, malachite usually has a distinctive green or green-banded pattern, while glass typically has a clear uniform appearance. The hardness of the material can also provide clues to help identify malachite from glass. Malachite is softer and can be easily scratched with a fingernail, while glass is harder and will not be scratched.
