XNN Cross Neural Networks


We kindly advise on the following care instructions for your jewellery, as we want you to enjoy your pieces for as long as possible.

1. SILVER CAREWhen you first receive your XNN/Softcore Hardware jewellery, it will be incredibly shiny. To keep this finish, never touch it or wear it, ever. Scratches and wear are inevitable. To maintain the polished finish of your silver pendant:
  1. Keep silver jewellery in a dry, cool place away from direct sunlight, heat, and moisture. Humidity can cause silver to tarnish quickly.
  2. Avoid contact with chemicals such as perfume, hairspray, lotion, and makeup. These products can react with silver and cause tarnishing.
  3. Wipe your silver jewellery regularly with a soft cloth to remove any oils and dirt that may accumulate on the surface. Avoid using abrasive or chemical cleaners as these can scratch the surface of the silver.

Please note that this natural aging will occur over time as the pendant grows with you. This is a good thing. Personally, I’ve been showering and perfuming mine for over a year and it’s gorgeous.
