First, the characteristics of Longshi
Longshi is characterized by gold, jade, stone and * * *. The stone part can produce beautiful colors of dark green, brown red and dark orange after pondering. After the metal part is polished, it can produce colors such as titanium, silver, gold and copper. The jadeite part can be polished to produce green, milky white, amber and other colors. Because metal can present different metal lines and jade inlay and shine after pondering, it is called dragon pattern. The name of the dragon stone came from this. The average hardness of dragon stone is about 5.5-6, which is smaller than the Mohs hardness scale (index 7) and similar to the hardness of glass. The hardness of human nails is 2.5.
The dragon stone weighs100t. After being polished by experts, it can stand like a statue, which is often found in hotel lobbies to demonstrate strictly. Dragon stones can be as light as grams. After the jeweler designs the hole, it can be processed into a necklace or bracelet, which brings a classic, noble and steady temperament.
The most sought-after type of Xiaolongshi is a round pebble, which has been washed by years and tumbled to the riverbed after repeated impacts. Round stones are not only easy to polish, but also easy to carry, which is a hot commodity for jewelers.
Second, the identification of Longshi
If the price is above 100 yuan, it can be basically confirmed to be true, but it can be determined whether it is natural or not, at least not C. This is the price.
If the material is translucent, look for fine lines inside.
If it is a good dragon pattern, look carefully for cracks, which will not only greatly reduce the price, but also change color if it is a bracelet.
As I mentioned earlier, C-grade gemstones are divided into three grades ABC. A-grade gems are pure natural, while B-grade gems are semi-natural, which is not good. After manual treatment, the C-class gem is fake.
The above knowledge about the dragon stone has been explained to you. I think you should know something about Longshi. In fact, the price of Longshi is not expensive. It is often used for decoration in our modern life, mainly for indoor and outdoor and ground, which can be seen in the building materials market. The largest dragon stone is measured in tons. But Xiaolong stone is more precious, simple to process and easy to carry, and it is very popular with jewelers at present.
