Surface Coating
Surface Coating refers to any treatment applied to gemstones to enhance their appearance or durability. It's like putting a clear protective layer on a gemstone to make it look better or last longer. This could include applying special substances that improve color, add shine, or protect the stone. When reviewing resumes in the gemology field, this term indicates experience with gem enhancement techniques. Similar terms include "surface treatment," "color coating," or "gem coating." It's important for gem professionals to understand these treatments as they affect both the value and care requirements of gemstones.
