- Does it contain real gold, silver, or metal clad with precious metal? → 7113
- Is the main decoration a natural or cultured pearl? → 7116.10

## Overlaps & pitfalls
A tie pin may combine materials (e.g., pearl with gold base), which could fit both 7113 and 7116.10. In such cases, prioritize the **main decorative element**—if the pearl is dominant, use 7116.10; if the metal is key, use 7113. If no real gem or pearl is present, even with a shiny look, it’s likely 7117
