Cleaning

At home, once a week

• Fill a bowl with warm water and a drop of mild dish soap.
• Soak diamond, sapphire and ruby pieces in gold or platinum for a few minutes.
• Brush gently with a very soft brush, behind the stone where lotion collects.
• Rinse under warm running water, with the drain closed.
• Pat dry with a lint-free cloth and let it air dry fully before storing.

Stones that need a lighter touch

Pearls, emeralds, lapis, malachite, onyx and other soft or porous stones should never be soaked. Wipe them with a soft, barely damp cloth and dry them at once. Keep them away from ultrasonic and steam cleaners.

Never use

• Toothpaste, baking soda or anything abrasive: it scratches gold and dulls stones.
• Bleach, chlorine or ammonia: they weaken gold alloys and solder joints.
• Paper towels or tissue on polished gold: the fibres leave fine scratches.

Gold and platinum

A dedicated polishing cloth brings back the shine between cleans. White gold is plated with rhodium; when it starts to look warm, we can re-plate it.
