紅銅 Copper
Copper has a high level of purity. Before oxidation, it has a rose-red color; after oxidation, it turns dark brown. This adds a warm tone to metal products, which are generally cooler in color.
When red copper oxidizes, it produces oxides that are harmless to the human body. However, when wearing red copper jewelry, these oxides can leave brown, gray, or black marks on the skin. If worn continuously, the presence of oxides will persist. If not worn, the marks will naturally fade after a few days.
For individuals with sensitive skin prone to allergies, it is recommended to choose hypoallergenic precious metals such as pure silver, 18K gold, or platinum.
