CARING PRACTICES

User Manuals

Avoid exposing your jewelry to harsh chemicals, such as chlorine, bleach, and ammonia. Remove jewelry before any physical activity, manual labor, sleeping, and showering.

Storage

Store each piece of jewelry separately to avoid scratches and tangles. Soft jewelry pouches and cloth-lined jewelry boxes are ideal for storing fine jewelry.

Maintenance

Clean your jewelry regularly to remove dirt and oil buildup. Use a soft cloth or a specialized jewelry cleaning solution to gently clean the surface of your jewelry.

Inspection

Have your fine jewelry professionally cleaned and inspected every 1-2 years to ensure that it remains in good condition.
