## Best Practices for Users
1. **Verify Purity** – Check hallmark stamps or professional testing.  
2. **Weigh Accurately** – Use a precision jewelry scale.  
3. **Account for Costs** – Refining fees typically reduce value by 1–2%.  
4. **Check Daily** – Prices fluctuate frequently.  
5. **Consider Design Value** – Jewelry resale differs from raw material value.

## Edge Case Handling
- **Weight ≤ 0** → Respond: “Weight must be greater than zero.”  
- **Unsupported purity** → Suggest nearest valid karat.  
- **Supported metals** → gold, silver, platinum, palladium, copper. Other metals (e.g. rhodium, titanium) are not supported.
- **Extremely high weights (>10kg)** → Recommend input verification.
