7000 nhiều năm trước, mankind had known jade and began to use it. The name “Ngọc” originated during the Spanish conquest of Central and South America, which means “smart stone” in Spanish. It is said that the Spaniards at that time believed that this jade had the ability to protect the body and resist various diseases. Vì thế, it has become the jewelry that people often wear.

TRONG 1863, French scientists confirmed that “Ngọc” is the general term for two different minerals and rocks. They are Jadeite and NephDhrite. The boundary between the two is difficult to define, Vì thế “Ngọc” is used as their common name. The name.

Jadeite and nephrite meet the requirements of “jadeness”, and they are minerals with tough texture and compact crystal grains, and both belong to “true jade”. The representative mineral of jadeite is jade from Myanmar, and the representative mineral of nephrite is Hetian jade from Xinjiang, Trung Quốc.

Dushan jade (fossil) produced in Nanyang, Henan, Xiu jade (serpentine jade) produced in Liaoning, màu ngọc lam (turquoise jade) produced in Xiangyang, Hubei, vân vân., because they do not meet the main conditions of “Ngọc”, namely The texture is tough and the structure is delicate and dense, so it can only be regarded as “like jade” instead of “true jade”.

‘Jadeite’ is equivalent to jade. After the jadeite entered China from Myanmar in the early years, this emerald green, smooth, crystal clear jade immediately robbed of the light of nephrite and became the favorite of collectors. “Nephrite” has always been China. The traditionally used jade, the commercial name is “mutton fat white jade.” Its origin is distributed in Xinjiang and Yunnan, Trung Quốc. It was used for Buddhist purposes in the early years, and later it was made into jade, jade seal, jade belt, jade pendant, jade paperweight, vân vân. China The similar jade produced includes Xiu jade, Dushan jade, hydrocalcium garnet jade, hard sodite jade, and quartzite jade.

The interpretation of the word Jadeite in the English dictionary is “Ngọc lục bảo” Và “Jadeite”. Can these two names be equal? According to the analysis of modern jewelers, “Jadeite” is not completely equivalent to “Jadeite”, but the jewelry industry refers to “Jadeite” as “Ngọc” Và “Jadeite” is also the commercial name of “Jadeite”. From a scientific point of view, jadeite is an aggregate of pyroxene minerals that are dense, massive, with high hardness, extremely tough and mainly composed of jadeite. The chemical formula of jadeite is NaAI (Si206). When its content in jadeite is as high as 99%, it is generally white; while green jadeite usually contains more diopside. Ngoài ra, jadeite may also contain a small amount of calcium iron pyroxene, chromite, albite and hornblende.
