## How to choose
- Is the button made of gold, silver, or metal clad with precious metal? → 7113
- Does it feature a real (natural or cultured) pearl as the main part? → 7116.10
- Is there a genuine gemstone (e.g., diamond, ruby)? → 7116.20
- Is it made of glass, plastic, or other non-precious materials to look like jewelry? → 7117
## Overlaps & pitfalls
A button with a gold setting and a fake pearl might fit both 7113 and 7117. Similarly, a rhinestone-studded button could be mistaken for 7116.20 if not verified. **No option takes priority**—choose based on the product’s MAIN material or defining feature (e.g., if it's a real diamond, use 7116.20; if it's fake, use 7117)
