Lapis lazuli is an alkaline aluminosilicate mineral, and its main mineral components are lapis lazuli, sodalite and copper sulfate. The secondary minerals are cryptocrystalline aggregates such as pyrite and calcite, which have granular structure and massive structure. The smooth surface is glassy to waxy luster, translucent to opaque, and the colors are dark blue, purple blue, sky blue and cyan.

With Tiffany, Cartier, Bulgari and other international luxury brands launching watches and jewelry made of lapis lazuli one after another, lapis lazuli, a precious ore from Afghanistan, has set off a "blue whirlwind" in the collection field. Fame is accompanied by rising prices. The price of lapis lazuli has doubled in a short time, and it is likely to become the next "tourmaline".
