The reason why gold jewelry is beautiful cannot be separated from the increasingly advanced craftsmanship. Gold jewelry without surface treatment cannot shine with dazzling luster, and different craftsmanship can showcase the different characteristics of gold jewelry. Below, the editor introduces five common craftsmanship.

1. Carving technique: Using diamond knives with different cutting patterns to rotate at high speed on the surface of gold jewelry, various carvings are cut. Car flowers can add exquisite patterns to jewelry, making gold jewelry more layered and three-dimensional.

2. Sandblasting process: After polishing the jewelry, high-pressure quartz sand or river sand is used to spray all or part of the exposed surface of the jewelry, forming a fine frosted surface. Sandblasting technology can make gold jewelry more textured and hazy, soft and beautiful.

3. Polishing process: Use a polishing machine to polish the surface of gold jewelry smooth and bright. Polishing technology can give the surface of gold a mirror like effect, showcasing the bright metallic luster of gold and making it look more shiny.

4. Ordinary wire drawing process: Using an imported sanding knife to pull the precious metal surface at a directional and uniform speed, forming a three-dimensional matte wire drawing jewelry surface. The brushed surface presents a shiny silk thread arrangement effect, enhancing the texture and delicacy of gold.

5. Stamping process: Stamping process, also known as die punching or embossing, is a manufacturing process for relief patterns. The commonly seen gold locks and other products are mostly made using stamping technology.

With the progress of craftsmanship and changes in aesthetics, people's enthusiasm for purchasing gold jewelry is also increasing. We hope that every partner can choose their favorite style~
