Thanks for choosing us! MOSUO jewellery pieces are made of 14 karat gold & Gold Vermeil and made to last a lifetime. We hope you handle your delicate pieces with love and care.

In order to keep your jewellery pieces in best conditions store them individually in an adequate jewellery pouch or box.

Avoid contact of the jewel with cosmetic products that can damage its color. Creams or perfumes can make your pieces darken due to the abrasion caused by chemicals. Vermeil, Gems and Enamel can be damaged by contact with chemicals such as creams, alcohol and perfumes. Especially pearls can be very sensitive to chemicals and should not come in contact with any cosmetics or detergents.

Don’t expose your jewellery to sudden temperature changes since the gemstones might undergo changes in colour.


How to clean gold jewelry ?

14 Karat Gold instructions:
You can easily clean your jewelry by yourself at home. Just soak your favourite piece in a glass of warm water with a drop of non-detergent soap (e.g. Dr. Bronner's).

Let it soak for a few minutes and pat dry it with a soft cloth.

Any remaining dirt particles can be removed carefully with a soft toothbrush.

 Gold Vermeil instructions:

To clean your Vermeil jewellery, use a clean cotton or microfiber cloth to buff it gently. Don't be tempted to use chemical cleaners as they can easily strip the gold finish.
