Diffusion

Diffusion in jewelry refers to a process used to enhance the color and appearance of gemstones and metals.

Part of speech: noun
Definition: Diffusion, within the context of the jewelry industry, is a specialized treatment process applied to gemstones and metals to improve their aesthetic appeal. By exposing the material to certain chemicals and high temperatures, the outer layers undergo changes in color or texture, which can enhance their appearance or mimic the characteristics of more valuable counterparts. This technique is particularly popular for treating sapphire gemstones, allowing for a variety of vibrant colors at a lower cost compared to natural, untreated stones. While diffusion helps in making high-quality jewelry more accessible, it's important for consumers to be aware of the treatment processes their gemstones have undergone to make informed purchasing decisions.
