CARE GUIDE

Take the proper care for your Patrick Boghossian jewellery so that your piece tells its story for a lifetime.

When using products like handgel, cream, perfume or applying makeup, we recommend removing your piece to avoid stains and wear on the delicate materials and gemstones.

Enjoy a complimentary professional cleaning of your piece at our London and Beirut locations. To clean your jewellery at home, use a soft toothbrush with warm soapy water and gently stroke the corners of your piece.
