How to Tell If You Have a Genuine Jade Stone

Updated March 23, 2017

Colour, markings, texture and overall appearance all play a significant role in determining whether your jade stone is real or fake. Identifying a fake is fairly easy once you learn the characteristics of authenticity. Closely observing and handling your stone will help you identify its characteristics and determine its real value. There are a number of tests you can perform on your jade stone to see if it is a clever fake or the genuine article.

Hold the stone up under a strong direct light. Look for dark green vein lines and cracks flowing through the stone. These are always present in authentic stones. If you don't see any flaws, or see air bubbles with light flowing through them, the stone is mostly likely not genuine jade.

Check the stone's temperature. Hold it in your hand. Authentic jade stones feel cool when touched, even in a warm environment. Close your hand around the stone and hold it until it feels as warm as your body temperature. Set the stone aside for about 30 seconds. Pick it up and touch the tip of your tongue to it. The stone should still feel cool, even though you warmed it with the heat from your hand.

Scratch the stone. Find an inconspicuous place on the stone. Use a piece of metal, such as the tip of a pair of blunt scissors or a small needle. Use the metal to gently scratch a small line across the stone's surface. Jade does not scratch easily. If the metal easily puts an indentation in the stone, the stone is probably fake.

Slide your fingernail across the stone's surface. Feel its texture for any bumps or flaws. The surface of a real jade stone has tiny cracks and crevices, so your fingernail will not glide over its surface without interruption. However, if the stone is not authentic, it may feel very smooth.

Tap the stone with a piece of metal or agate. If it's authentic, it should produce a high-resonating sound similar to a chime or bell. Imitation jade makes a sound similar to that of two wine glass clinking together, or marbles rattling in a jar.

Examine the stone's colour. Real jade stones come in green, blue and lavender. The colour should look opaque and cloudy, with shade variations. If the colour looks uniform, the stone is probably artificial.
