The lapis lazuli, which has been so popular for a few years now, is so hot. After the turquoise, the lapis lazuli has quietly approached the jewellery and jade market, and occupied its own "blue sky." So today, Xiaobian will walk into this mysterious "blue ocean" with you.
Symbol of the nobility
Whether it is China or Babylon, Egypt, lapis lazuli is a symbol of power and represents the right and wealth. Only people of a special class can have it. The lapis lazuli itself is soft in texture, so the craftsmen often engrave on its surface to highlight its luxury.

Although the production of lapis lazuli is very high, it is rare and rare. Therefore, the lapis lazuli as a "patent" of the nobility is also worthy of the name.
What is lapis lazuli

The price is close.
How to choose
In the jewellery and jade industry, lapis lazuli can be divided into two levels, gemstone and commercial, according to international popular practices. Gem-quality lapis lazuli is commonly known as lapis lazuli for jewellery. It is usually divided into three levels according to the color depth and whether it contains pyrite:
Gemstone level: dark purple with a slight purple color, uniform color distribution, strong luster, completely free of pyrite and calcite;
Gem II: pure blue or purple blue, uniform color distribution, strong luster, completely free of pyrite and calcite;
Grade III of gemstone: The optical characteristics are the same as that of gemstone and gemstone, but it contains pyrite and pyrite. It is a striking star-like dispersion distribution, which is equivalent to the Jinge wave variety.
The lapis lazuli is preferred in terms of uniform color and no cracks, fine texture without gold stars or beautiful Venus. If Venus is black, dark, or has too much calcite to form a large area of ​​white spots on the surface, the value is greatly reduced. The fine lapis lazuli texture is fine, slightly transparent or translucent, azure, covered with punctate pyrite.
How to identify
Although the lapis lazuli is not easy to imitate, the huge interests have also driven some unscrupulous businesses to carry out fraud. Quartzite, resin, glass, etc., which are often used to imitate lapis lazuli, are hard to prevent. People who love lapis lazuli generally know that the texture of lapis lazuli without white and gold is good, so unscrupulous merchants will dye some lapis lazuli that cannot reach this level, and shoddy it. This is also a need to beware.
Investment guidance
The lapis lazuli mine is rich in production, but the lapis lazuli that can reach the gem-quality standard is extremely rare. Therefore, when you want to invest in the value of lapis lazuli, you must choose the jewel-grade lapis lazuli to buy; many people think that lapis lazuli The more Venus, the better the quality. In fact, the opposite is true. The Venus and White Line in the lapis lazuli are all impurities of lapis lazuli. Therefore, the fewer the white lines, the better. At the same time, the fewer Venus, or the more golden the color, the more evenly distributed. The lapis lazuli is the best.
Many people like lapis lazuli because its blue color is full of gold and white spots. Therefore, many jewellery products will choose lapis lazuli with more impurities to be designed as relatively inexpensive and creative jewelry. If you only use it for decoration, Then this type of jewelry is very suitable.
