1, Hardness: The high hardness of titanium is its inherent advantage, which can not only make jewelry hard enough, but also prevent jewelry from being scratched.

2. Properties: The chemical properties of titanium metal are very stable. It won't change color tone at room temperature, and it won't be oxidized to black like silver. This feature can highlight the advantages of designing and making rings, which can satisfy the kind of "stability" you are pursuing, both in actual products and in concept.

3. Color: Usually, the surface of titanium is silver gray, but if it is electroplated at different temperatures, an oxide film will be formed on the surface of titanium. The reflective optical fiber on the surface of the oxide film interferes with the light reflected by the transparent oxide film and the metal interface, forming various colors. This interference color changes with the thickness of the film, showing colorful colors.
