Exposure to chemicals can damage and discolour various metals (silver, gold and niobium) and may harm some coloured stones. Fine jewellery should be removed before entering a chlorinated swimming pool/hot-tub or before using household cleaners.
To help prevent tarnishing of sterling silver, store your jewellery in an anti-tarnish jeweller's pouch or place it inside a plastic ziplock bag.
To remove tarnish, polish with a Hagerty polishing cloth or if excessively tarnished, our Hagerty dip. Be sure to rinse with clean water and dry thoroughly. Be sure to read detailed directions on the back of all Hagerty packaging.
Never use toothpaste as it can be gritty and abrasive.
Soak for 15 minutes in a solution of two cups warm water and a few drops of a mild dishwashing liquid. Gently scrub with a soft-bristle toothbrush. Rinse with warm water, and dry with a soft cloth. Follow with a polishing cloth to restore the lustre to the gold.
Fingerprints, body oils, lotions, perfumes and hairspray will make the bright colours of niobium look dull, but niobium can be easily cleaned with warm, soapy water and dried with a soft cloth.
It is usually recommended to clean most coloured stones in warm water, mild soap, and a soft brush.
The following coloured stones are especially sensitive to wear, heat and chemicals. They scratch more easily, so should be stored very carefully. Intense heat or light may alter their colour. Any alcohol based chemicals such as perfumes and hairsprays may also alter their colour or dry them out.
