Looking for the best way to restore dull pearls?
The Pearl Refresh Cloth, developed by Pearl Science Laboratory, the world’s leading pearl institute known for its Hanadama Pearl certification, is designed to gently remove micro-scratches and bring back your pearl’s original shine.
Why Choose Pearl Refresh Cloth?
✔ Removes micro-scratches that dull pearl luster over time.
✔ Infused with fine polishing agents to gently refresh the outermost pearl layer.
✔ Safe for pearls – Only removes 0.3–0.5 microns of the pearl surface, ensuring no damage to the nacre.
✔ Easy to use – Simply wrap the pearl and gently rub to restore its brilliance.
📆 Recommended use: Once every 6 months for optimal pearl care.
💎 Also suitable for precious metals.
