Amber is a resin secreted by thousands of years of coniferous plants. It is buried in the underground and formed by fossils. Due to the precious value of amber, many imitations have appeared on the market. So how do you identify amber?
"Salt Method": When amber is placed in water, it sinks to the bottom of the water. Then, the dissolved concentrated brine is continuously added thereto, and when the salt concentration is more than 1 to 4, the true amber will slowly float.
"Needle Burning Method": When a needle is heated, it quickly approaches the surface of the amber. The melting point of the amber is very low. When it is heated, it melts locally and can also smell a light pine scent. The more obvious the taste, the higher the purity.
Amber often has bubbles, fragments, and cracks in its formation, so if each of the beads of an amber necklace is very similar and transparent, or if the insects contained in amber are complete, it is likely to be a fake.
If the natural amber is placed under the money detector, it will be light green, green, blue, white, etc., while the synthetic amber will not change color.
