Do All Metals Oxidize?

Gold Jewelry
Pure gold and high-karat gold jewelry (24K, 22K, 18K) are generally resistant to oxidation under normal conditions. However, jewelry made from lower karats such as 9K, 10K, and 14K may gradually lose their luster over time due to the higher proportion of alloy components.

Silver oxidation is a natural phenomenon. Silver is an active metal that easily reacts with elements in the air such as sulfur, nitric acid, and oxides, forming silver sulfide on its surface, which is commonly seen as tarnishing or blackening. Additionally, silver can also be affected by the environment and the wearer. For instance, some people's sweat contains more acid or higher sulfur content, which can cause silver jewelry to tarnish. Everyday cosmetics, perfumes, lotions, and other chemical products used can also contain substances that may oxidize the metal.
To delay the oxidation of silver, it is essential to isolate it from direct contact with the air. For this purpose, TING H Jewelry has introduced rhodium-plated sterling silver, which adds a layer of protection to the silver by electroplating it with rhodium, isolating it from direct contact with the air. This also enhances the overall luster, making it more elegant and bright.
