✔ Lacquer Spray → Clear coat for long-term shine
✔ Jewelry Sealants – E.g., ProtectaClear

6. ضبط الجودة & التغليف

6.1 Inspection Checklist

✔ No sharp edges (الايداع & smoothing complete)
✔ Patina consistency (No unintended blotches)
✔ Ring size accuracy (Test on mandrel)

6.2 Packaging for Retail

  • Anti-Tarnish Pouches (Prevent oxidation during storage)

  • Branded Boxes (Luxury presentation)

7. اتجاهات السوق & الفرص التجارية

7.1 Popular Antique Brass Ring Styles (2024 الاتجاهات)
