Jade identification method
Jade can be divided into two types: nephrite and jadeite, and jadeite is also known as jade. From the chemical point of view, nephrite is a silicate containing calcium, magnesium and iron, while jadeite is a silicate containing sodium and aluminum.
Here are some common methods for identifying true and false jade:
(1) Water identification method
Put a drop of water on the jade. If it is in the form of dewdrops, it will be true jade for a long time.
(2) Hand touch method
If it is true jade, feel cold and lubricated by hand.
(3) Observation method
The jade is observed against the bright spot, and the color is clear and the green is evenly distributed.
(4) Tip of the tongue
The tip of the tongue is really jealous, but the fake jade is not.
In addition, it can also be observed with a magnifying glass, mainly to see if there are cracks, and the value of cracks is greatly reduced.
