1. color: bright silver is pure silvery white, giving people a bright and clean feeling. However, the oxidation of natural color may show a yellow tone or a deeper oxidation color.

2. Oxidation process: Bright silver is not polished, and its oxidation process is usually faster. Natural color oxidation can be carried out by different methods, such as thermal oxidation or chemical oxidation, and the oxidation speed is relatively slow.

3. Application scenario: Bright silver is usually used in jewelry, decorations, works of art and other occasions that need to show bright and pure effects. Products with natural color oxidation are more suitable for some works of art that need to have specific requirements for oxidation effect or express specific emotions.

Generally speaking, the difference between bright silver and natural oxidation mainly lies in color, oxidation process and application scenarios.
