Oiling

Oiling refers to the process of applying oil to gemstones to enhance their appearance.

Part of speech: noun
Definition: In the jewelry industry, oiling is a widely used enhancement technique for gemstones, particularly emeralds, aiming to improve their clarity and overall appearance. By filling cracks or fissures on the surface of the gemstone with a light oil, this treatment decreases the visibility of imperfections and enhances the stone's natural beauty. The oil used can range from clear oils to those with a slight color to better match the gemstone. While this method can significantly augment a gemstone's aesthetic appeal, it is generally considered a temporary enhancement, as the oil can wear off over time or be removed through cleaning and handling. Consumers are often advised to re-oil these gemstones periodically to maintain their enhanced appearance.
