Jade has the reputation of the king of jade. In China's gem and jade industry, there is a saying that yellow is jade and green is emerald. Jadeite is a kind of jadeite in jade. Its mineral structure is carpet like, with glass luster or pearl luster. It is often translucent, and a few are full transparent, known as "glass pieces". The jadeite jade is mainly produced in Myitkyina Menggong area in northern Myanmar.

Pure gold is too soft to inlay various exquisite styles, especially precious stones. Therefore, people add silver, copper, zinc and other metals to pure gold to increase the strength and toughness of gold, which is called decoration gold. The production of determining the content of pure gold in jewellery gold is called "gold position", which is karat in English and translated as "open", abbreviated as "k". Therefore, jewelry is also called "K" gold. Pure gold is 24K, that is, the gold content is 100%. Therefore, 1K gold jewelry contains 1/24 of pure gold, about 4.16%. 24K and 18K are popular in China, while 14K or 12K gold is popular in Europe and America to inlay jewelry.

5. What are goods A, B and C?

Product A: refers to authentic natural jadeite without any fake treatment. The high-grade products are green and dripping, with good but not evil colors, good water head, no impurities, no grain cracks, and will not change color for a long time, so they have good value of preservation and collection.

Product B: It refers to the natural jadeite with poor quality that is soaked in concentrated acid and bleach to remove black and yellow. After being treated with special methods such as epoxy resin filling, the water head becomes better and the color becomes beautiful, and the real jadeite changes color.

Product C: It refers to the colorless jadeite jade that is heated and dyed manually, also known as "colored jade", which is a category of "true jade and false color". It is unnatural in color, often with blue or yellow components, dull in luster and uneven in color.

6. What is "head"?

In the jade industry, transparency is called "water head", good transparency is called "water head enough", poor transparency is called "no water head" (or dry). For jadeite, when the color is good (green), water head enough is called "colored has seed", and its value is high. On the contrary, good color and head difference are called "colored and colorless", and good head and color difference are called "seeded and colorless". The latter two are of low value.

Generally, the large jadeite gravels produced in Myanmar that are naturally transported to river valleys and river beds are called "old pit jade" or "young materials". This kind of jade is characterized by "good water head" and hard quality. Its top grade is as transparent as glass, so it is called "glass piece" or "ice seed". The green jade is called "high green" or "bright green". However, the newly mined jadeite jade in the original place has no weathering skin, and its water head and luster are worse than those of the old pit jade. It is called "new pit jade", also known as "mountain jade".

The "ground" is the bottom color of jade, or "bottom". Generally speaking, jadeite jade is called Dizi except for its emerald green color. The quality of the land has a very important relationship with the value of the overall jade. The better ones are glass floor and lotus root powder floor, the middle ones are soybean green floor, blue and white floor and purple flower floor, and the worse ones are porcelain floor and dry white floor.

In jadeite, small lumps with slightly less transparency are often interwoven with fibrous crystals, which is called "stone flowers". It can be divided into several categories: the more dry and rigid is called "Shi Nao"; The broken ones are called "reed flowers"; Cotton like is called "cotton"; White or green mixed together is called "leek mixed with tofu". In general, the existence of stone flowers is not good for jades, and it is easy to have a negative impact on green, thus significantly reducing the value of jadeite.
