## Overlaps & pitfalls
A chain with real pearls and a gold clasp could fit both 7113 and 7116.10. In such cases, **the main decorative element determines the classification**—if pearls are the focus, use 7116.10; if metal is dominant, use 7113. If a product combines real stones and imitation parts, prioritize based on **main function or visual prominence**. No option takes priority by default—choose based on the defining feature
