Use & Maintenance

Your Kern jewel has been designed with great care according to the requirements and rules of the jewelry industry. Each step of the manufacturing process has been carried out with the utmost care, in order to create an exceptional piece. To keep it looking its best, we recommend that you carefully follow our maintenance tips:

Tips for use

When you are not wearing it, it is preferable to store your jewellery in its original case or pouch, thus avoiding rubbing with other jewellery, shocks and scratches.

When wearing your jewelry, be sure to handle it gently to avoid bumps and falls. It is preferable to remove your jewellery when practising sports.

Avoid contact with salt water, sand, cosmetics, perfumes, detergents and any corrosive product that could alter precious metals and gems.

We recommend that you have the condition of your jewellery checked every year. Do not hesitate to make an appointment with our workshops to have the crimps, clasps and their double security checked. During this visit, our jewellers will know how to revive the brilliance of your pieces and give back to the gems all their vivacity.

Maintenance instructions

To intensify the shine of your jewelry, do not hesitate to rub them with a soft and dry cloth. If you wish to clean them, you can immerse them in soapy water (PH neutral soap) to eliminate impurities due to pollution.

Then rinse them with clean water and dry them carefully with a soft cloth.

This procedure does not apply to bracelets set with emeralds, for which we recommend special attention.

Polishing and rhodium-plating operations, which are effective in restoring the shine to your jewellery, cannot be repeated too frequently.

The first polishing and rhodium plating are offered by Kern. The following, which should preferably be carried out in our workshops, are at the customer’s expense.
