How is jadeite raw stone formed? How to tell whether jade is authentic?

Jade is a precious gemstone that originates from deposits deep within the earth. The formation of jade is closely related to the dynamics and geological processes of the earth's crust. Under the high pressure and high temperature environment of the earth's crust, the reaction of silicon monoxide in the rock with other elements forms jadeite raw stones rich in magnesium silicate. This process can take millions of years or even longer.

🔬 How to distinguish the authenticity of jadeite🔬

Distinguishing the authenticity of jade is a task that requires experience and expertise. Below, I will introduce some commonly used methods to judge the authenticity of jadeite.

1️⃣ Appearance observation: Real jade usually has a delicate and uniform green color, and the color is relatively full. The color of fake jade may be uneven, and sometimes patches or bands may appear.

2️⃣ Optical inspection: Use a magnifying glass to observe the internal structure of jade. Real jade usually has a fine texture and a bright luster, while the texture of fake jade may appear rough or fuzzy.

3️⃣ Temperature sensing: Place the jade in the palm of your hand or rub it and observe its temperature changes. Real jade usually has a higher thermal conductivity, so it will feel cooler. Fake jade usually feels warmer.

4️⃣ Fluorescence detection: Place the jade under ultraviolet light and observe its luminescence. Real jade will usually emit green or light yellow fluorescence, while fake jade will often not have this reaction.

5️⃣ Density measurement: Use a densitometer to measure the density of jadeite. The density of real jade is usually between 2.90 and 3.03 g/cm3, while the density of fake jade may deviate from this range.

It should be noted that these methods are for reference only. When judging the authenticity of jadeite, you should use a combination of methods and try to find an experienced professional appraiser to make an accurate identification.
