What to look for when inspecting antique jewelry:
- Mold Lines: There are telltale signs of a machine piece so look for mold lines.
- Color: A synthetic or simulant has a evenly distributed color.
- Patterns: If a pattern is randomly distributed it generally indicates a natural product while a repeating pattern usually means it is synthetic.
- Hallmarks: There are hallmarks that help identify the material including signatures, patent or design numbers, country of origin and metal content.
Guidelines and criteria can include weight, sound, odor, Bakelite, bog oak and more. To learn more and become an expert in antique jewelry start with:
