Things You'll Need
Instructions
Check for air bubbles. If there are any, it's treated glass, not jade.
Put the jade in your hand. Jade is dense, so should be heavier than glass and most other rocks of similar size.
Scratch the rock with a steel scrubber. Jade doesn't scratch.
Wrap a strand of hair tightly around the jade. Hold a flame to the hair. If the hair burns, the rock is not jade; jade would have absorbed the heat.
Touch the jade to your cheek. Jade should feel cool in most environments.
Hold the jade in one hand and hit it with a rock using the other. Jade should make a resounding sound.
Run your fingernail along the stone. If it's bumpy, it's probably not jade.
Try chipping or breaking it. Jade is extremely durable so it shouldn't chip or break easily.
