1. The choice of materials for making high-grade jewelry cannot be ignored. Only in this way can we call it high quality jewelry, and quality assurance is the most important. Precious metals (gold, platinum) are the best materials for inlaying high-grade jewelry, because such materials are more valuable. In addition, precious and rare semi precious stones, precious stones and high-quality diamonds are the inevitable choice of high-grade jewelry materials. Nowadays, with the development of science and technology, most gemstones on the market are artificially processed to exaggerate their own value. Therefore, high-quality jewelry inlaid with 100% genuine natural gemstones (if not heated) is the best choice for quality assurance.

2. Each brand has its traditional and unique design and inlay technology. Unique craftsmanship and the personality and characteristics of brand works are indispensable elements for any piece of high-grade jewelry. In addition to some striking styles, it is a key consideration for craftsmen when creating high-grade jewelry to show the brilliance of the material itself and let the gemstones give play to their restrained but elegant and shining luster. Perfect handwork, flexible changes and meticulous design are all necessary conditions for the creation of high-grade jewelry. An "excellent" piece of high-grade jewelry will make any wearer show a "beautiful" effect after wearing it.

3. The historical value of high-class jewelry should be appraised. In addition to the design style, it is to see the rarity and guarantee value of gemstones embedded in high-class jewelry. With the change of nature and the exploitation of human beings, there are few natural minerals. There are fewer and fewer opportunities to discover pure natural, high-quality and high-quality gemstones. Some gem producing areas have even disappeared. Therefore, a high-quality rare gem, such as the sapphire in Kashmir and the Burmese ruby, has a very high historical preservation value. To determine the historical value of a piece of high-grade jewelry, it is necessary to first determine the naturalness and authenticity of the quality of the gem, so the gem certificate can be said to be a certificate of value of a piece of high-grade jewelry. In order to determine the authenticity of antique jewelry, the experience of the connoisseur, the assistance of instruments and the evidence of certificates are necessary.

4. Artistic sense creates jewelry craft, and "aesthetic sense" can be said to be the condition that people pursue. The inspiration for creation usually comes from real life. In the form of simulation, every bit of real life, such as the animal and plant forms of nature, human emotions, is transformed into extraordinary jewelry works. Among them, "aesthetic feeling" is an important element of creation. "Like in shape is not like in spirit". A successful jewelry work should be able to experience the deep beauty and charm of the inspiration source from the work. The unique quality of inspiration will be fully reflected in the works, making the works contain unlimited ornamental and artistic value.
