Jewelry is a kind of exquisite crafts with special materials. It will inevitably put forward different material requirements for different production materials. This is the fact. Among the various natural or synthetic gem materials used in jewelry, people have also proposed the rough shape, size, color, transparency, material uniformity and defects, and special optical effects. [...]

Gems are formed due to geological changes. Most of the gems are minerals or rocks naturally formed in the crustal rock layers, which usually take more than ten million years. Due to different geological conditions, the production area is also different, mainly depending on the mineral or rock properties formed by Baogou. Minerals have a [...]
Since every gemstone has its own specific conditions of formation, chemical composition and internal structure, there is still no uniform classification scheme in the world. How to classify gems scientifically and reasonably is a topic of common concern in the international jewelry industry. At present, countries around the world agree with the classification of gems [...]
In nature, all materials that have bright colors, crystals, and brilliance; pure texture, hard and durable; excellent craftsmanship; rare characteristics that can be processed into jewelry and handicrafts can be called gems. These materials include: natural mineral crystals (single crystals and crystal aggregates), amorphous rocks, and natural organic materials and man-made materials. Generally speaking, unprocessed [...]
So far, more than 4,000 kinds of minerals have been discovered in the world, of which nearly 600 can be called gems, and about 30 common gems. The factors considered for the classification of gems include: the genetic type of gems, the habits and traditional culture of the international jewelry industry, and the traditional Chinese [...]
The reason why gems are called "treasures" is their beautiful color. So what is the attractive color of gems? Where did it come from? Color is an electromagnetic wave that can be felt by the human eye with a certain wavelength. Its wavelength range is about 400-700 nm in the electromagnetic spectrum, also known as [...]
In chromatology, the three elements of hue, lightness and saturation are used to describe colors. Hue, also called hue, refers to the distinguishing characteristics of red, orange, yellow, green, cyan, blue, and purple. The hue depends on the selective absorption of visible light by the gem. Brightness, also known as brightness or hue, is the [...]
The beauty of gems comes first in color. In addition, transparency and luster are all its charms. Transparency refers to the ability of a gemstone to transmit light. Usually divided into: transparent, translucent, translucent, translucent, opaque. Transparency: easy to see through the light, clear bottom, the outline and details of the scene can be clearly [...]
The ability of a gemstone to resist pressing, scoring or grinding is called its hardness. The hardness of a gemstone is related to its chemical composition, chemical bond and crystal structure. Hardness is one of the three essential elements of gemstones, and it is also a problem that must be paid attention to in gemstone [...]
Electrical conductivity is the ability of a gemstone to conduct electricity. It largely depends on the type of chemical bond. Gems with metal bonds are highly conductive because they have free electrons in the crystal structure, while ionic bonds or covalent bonds are weak or non-conductive. In addition, the conductivity of gems is also related [...]
