In terms of materials and forms of expression, there are four types of jewelry:

I. Precious jewels

The materials used are mainly precious metals (platinum and gold) and precious stones (diamonds, rubies, emeralds and emeralds). The metalworking is exquisite, and the inlay and surface treatment are very particular.

Second, popular accessories

Fashion accessories mainly cooperate with fashion and emphasize fashion. Use materials to break through the limitation of expensive materials, and all materials that can play a design role can be used. Metalworking is not as delicate as precious jewelry, and most of the inlaid parts are fixed with adhesive.

Third, the bridge ornaments

Made of silver, gold, artificial gem, colored gems, etc. It is called bridge jewelry because its value and quality are between precious jewelry and popular jewelry, just like a bridge between them.

Fourth, art jewelry.

The use of materials is unrestricted, and jewelry becomes a form of artistic creation, conveying the creator's thoughts and emotions. Metals and gems are simplified into simple creative materials, and unique works of art are constructed through the originality of the creators.
