How should I care for my jewelry?
To keep your jewelry looking its best, avoid contact with harsh chemicals, remove it during strenuous activities, and store it separately in its original box or pouch.
We recommend gently wiping your jewelry with a soft cloth after wearing.
Use the mild jewelry-specific cleaning solution. Avoid harsh cleaners and abrasive cleaning tools, as they can cause irreversible damage to the jewelry and metals.
Pearls are unique organic gemstones. Avoid exposing them to perfumes, lotions, hair sprays, or cosmetics. Prevent them from coming into contact with sharp or abrasive objects to avoid scratches or abrasions.
