The Science Behind White Gold’s Color Change
Understanding the composition of white gold and its natural hue is crucial to comprehending the reasons behind its color change. White gold is an alloy made by combining pure gold with other metals, such as silver, palladium, or nickel. The addition of these metals alters the color of gold, resulting in a white or grayish appearance.
The natural color of white gold, without any additional treatments or platings, has a slightly yellowish tint compared to pure silver or platinum. This subtle hint of yellow is due to the presence of other metals in the alloy composition.
Rhodium plating is a common technique used in the jewelry industry to enhance the whiteness of white gold. Rhodium, a metal in the platinum family, is applied as a thin layer onto the surface of white gold pieces. The rhodium plating gives white gold jewelry a bright, reflective, and pure white appearance, effectively concealing any yellowish tints.
By using rhodium plating, jewelers can provide a consistent and attractive color for white gold jewelry. However, it’s important to note that rhodium plating is not a permanent solution. Over time, the thin layer of rhodium can wear off, revealing the natural color of white gold underneath.
So, while the composition of white gold and the role of rhodium plating contribute to its color change, it’s essential to understand that white gold’s natural hue may differ from the pure white color associated with other metals.
