Jade is a beautiful and highly sought-after gemstone that has been used for centuries in jewelry, sculptures, and other decorative objects. However, with the rise of counterfeit jewelry and gems in recent years, it can be challenging to tell if the jade you’re looking at is genuine or not. In this article, we’ll explore the different methods used to determine if jade is real.
-
Visual Inspection
The first step in determining whether jade is real is to visually inspect it. Look for any air bubbles, cracks, or other imperfections. If the stone has a perfectly smooth surface, it’s likely a fake. Real jade also has a waxy or oily appearance when held up to light, while a fake will look more like glass.
-
Sound Test
Jade is a dense stone, so it will make a clear and ringing sound when struck. To perform a sound test, lightly tap the stone with a metal object. If the sound is dull or flat, the jade is likely fake.
-
Thermal Conductivity Test
Another way to tell if jade is real is to perform a thermal conductivity test. Real jade will feel cool to the touch, even in warm temperatures. Hold the stone in your hand for a few minutes, then press it against your cheek. If it feels cool, it’s likely real jade.
-
Scratch Test
Jade is a hard stone, so it’s difficult to scratch. You can perform a scratch test by rubbing the stone with a piece of metal. If the metal leaves a scratch on the surface, the jade is likely fake.
-
Density Test
Real jade is denser than fake jade. You can perform a density test by weighing the stone and then measuring its volume. Divide the weight by the volume to determine the density. If the density is close to 3.3 g/cm3, it’s likely real jade.
In conclusion, there are several methods you can use to determine whether jade is real. These include visual inspection, sound tests, thermal conductivity tests, scratch tests, and density tests. If you’re unsure whether the jade you have is real or not, it’s best to take it to a professional jeweler or gemologist for an expert evaluation.
