Wear & Care

  • To delay the natural process of oxidating, we advice you to keep your piece of Kolmnurk™ Jewelry in a closed box, and keep it away from perfumes and water. Remove it when swimming, exercising and sleeping. We understand if you wish to wear your piece of jewellery 24/7, just be aware that the string will need a replacement faster that way.Kolmnurk™ Jewelry uses 18k or 14K goldplated and sterling silver .


  • Sterling silver is an alloy of silver which will naturally oxidate after a while, being exposed to air and the natural oil level of the skin. We advice you to polish your jewellery once a month with the complimentary polishing cloth you received with your order. You can also use silver cleaning products, just make sure you don’t stain the string.


  • Our 18k gold pendants are made of brass with a layer of gold. Normal use will eventually lead to oxidation. If and when this happens depends of the acidity of your skin.We advice you to polish your jewellery once a month with your complimentary polishing cloth. The string we use is made in UK. How long it lasts depends on the usage. After a while, the string can show discoloration and might need a replacement. Our jewelries are made of 18k or 14k gold-plated or Rhodium plated Sterling Silver.
