A KOSINER piece is a timeless investment. Looking after your jewelry properly will help maintain its splendor, shine and lifespan. Below we’ll offer you a few useful tips on how to care for and maintain your jewelry. 


Maintaining shine

All KOSINER articles have been treated with a technique that helps to prevent loss of shine.

However, it is still important that you follow our suggested care instructions.

  • Your jewelry can lose its shine when exposed to air during a long period of time.
  • Loss of shine or tarnishing is a natural process that can be recovered through a special washing.
  • We strongly recommend taking off your jewelry before going to bed, showering, or taking part in any physical activity.
  • Exposure to certain chemicals or environments may compromise the integrity of your jewelry. This includes (but is not limited to): perspiration (sweat), perfumes/colognes, cleaning products, chlorine, salt water, or silver polish, etc.


Cleaning jewellery

Mix a little soap with lukewarm water and rub the item with a soft toothbrush. Toothbrushes are perfect for cleaning jewellery with difficult-to-access corners. If dirt persists, carry out the same process in clean water. Important: gold-plated items require greater care. Rubbing too hard may cause loss of plating. It is therefore important that you do this gently in order to avoid any damage. A special silver-polishing cloth is a great tool to make your jewellery shine again, in the event that it becomes darkened over time. However, this technique will not remove any scratches or dents present on the jewellery.


How to preserve jewellry

Your jewellery should be kept away from any exposure to sunlight or warm places, ideally in a padded jewellery box or tarnish-resistant bag. You can also keep these in individual airtight plastic (polyethylene) bags. Never use rubber containers, as these can result in accelerated tarnishing and are likely to cause the jewellery to darken. Under no circumstances should you keep your jewellery in a bathroom or any humid locations. Keep in mind that KOSINER boxes are not designed to keep items in perfect condition for prolonged periods of time, as they are not airtight containers, and colour alteration may occur due to lack of use.


Please note:

KOSINER cannot guarantee that the gold-plating of our items will last forever. Gold-plated items are, by their nature, more fragile and susceptible to lose colour over time. The speed at which this colour fades will depend on various factors, such as the use of chemical products on the skin, how much the wearer sweats, or even the pH level of the individual’s skin. For this reason, it is particularly important to ensure suitable care of your gold-plated jewellery.
