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.

Quality of the Gems

The white diamonds used by Kern are of GVS quality

Provenance: Canada, Republic of South Africa and Namibia.

G indicates extra white. The classification ranges from D, for exceptional white +, to Z for highly coloured diamonds.

VS, for Very Small Inclusion, determines the purity of the stone, meaning that the inclusions are hardly visible with a X10 magnifying glass.

SELECTION OF OUR DIAMONDS : Respectful of the Kimberley processKern is committed and responsible and places the utmost importance on the origin of its diamonds. They come from legitimate, authorized sources not involved in the financing of armed conflicts and in compliance with United Nations resolutions.

The Kimberley ProcessThe diamond industry is committed to ensuring that no rough diamonds in circulation on the world market are “conflict diamonds”, as initiated in 2000 by the UN, diamond producing states, the diamond industry and NGOs. Today, it brings together more than 80 countries, representing the vast majority of players in the rough diamond production and trade.

In January 2003, the Kimberley Process Certification Scheme (KPSC) came into effect, in order to reinforce the traceability of gems. Under this certification system, all rough diamonds must travel in sealed containers and be accompanied by a numbered certificate of origin issued by the government authorities of the exporting country. https://www.kimberleyprocess.com

Kern selects AAA quality sapphires

Origin : Ceylon

We speak of an “A” quality gem for a good quality stone, “AA” when the quality is superior, and “AAA” when the stone is truly exceptional. Generally speaking, quality refers to the beauty and intensity of colourto the transparency of the stone (the more transparent the stone, the more quality it can claim to be), and finally to the quality of its cut.

The black diamonds of the House of Kern

Origin: Australia then processed in Israel

In order to obtain a homogeneous color and a beautiful brilliance, the black diamonds used for our Kern creations have been treated in order to embellish them and to obtain an exceptional intensity and hue.

Brown diamonds (chocolate) from the House of Kern

Origin : Australia

Of natural color and not treated, the brown and champagne diamonds present a brightness guaranteeing their vivacity.

The emeralds of the House of Kern

Provenance From the Ural Mountains, India, Brazil, Zambia, Pakistan and Colombia.

Emerald is not a soft stone, but it is naturally embedded with internal frosts that make up the emerald garden. Weakened by its natural structure, it requires more attention than other gems.

It is advised not to expose emeralds to strong heat, sun and thermal shocks. It is best to avoid contact with chemicals, such as cleaning products, cosmetics and perfumes.

The tsavorites of the Kern House

Origin Tanzania and Madagascar

The tsavorites are a variety of garnet that we propose in gradient with different shades of green color on our creations. It gets its green colour from traces of vanadium and chromium.

This stone is rare, (it is estimated that there are still 200 times less on earth than there are emeralds), unknown, and almost devoid of inclusions. There are soft green tsavorites, and others bottle green.

The blue diamonds of the House of Kern

Origin: Australia, South Africa, India

Blue diamonds owe their colour to the presence of Boron in the heart of their structure, thus requiring particular geophysical conditions for their formation. This explains why only three mines in the world produce the bulk of natural blue diamonds.
