Jewelry cleaning

2, after cleaning jewelry, you can put it on a towel without cotton wool to dry.

3. Use wax-free dental floss or toothpicks to remove dirt on gems and between claws.

5. Avoid washing with washing powder, detergent and toothpaste containing abrasives.

6. Do not put it into detergent or acid solution for cleaning.
