Daily Care Advice - About Metals

There are many reasons that cause oxidation. Daily care is a good way to keep your jewellery accompany for a long time.

❍18K Gold、 14K Filled Gold、Sterling Silver ❍

Wipe the metal surface with a silver polishing cloth. Soak in silver cleaner water for 3-10 seconds for heavy oxidation and rinse with clean water. Store in a sealed bag after drying. It is not recommended to clean inlaid gemstones with silver cleaner water. This is to avoid damage to the gemstones. Please seek professional help from the OYJ Jewellery doctor.

❍Electroplating Jewellery ❍

Wipe with a moist soft cloth and store it in a sealed bag after drying. To remove the obvious oxidation on the surface, it can be gently wiped off with a silver polish cloth. If the electroplating layer peels off from the surface, it can be re-plated by OYJ. Please avoid contact with alcohol, silver cleaner water, silver polish cream, soap, hot springs, and seawater.

Daily Care Advice- About Gemstones

 ❍ Pearl / Opal / Moonstone / Calcite ❍

If it gets stained, simply wipe with a soft moist cotton cloth and store it in a zipper bag after drying. This type of jewellery is low in Mohs hardness semi-precious gemstones, therefore the surface can be easily scratched or damaged. If this happens, gemstones can not be repaired. Please be advised not to expose it to sunlight for a long time.

Please avoid contact with perfume, alcohol, silver cleaner water, silver polish cream, soap, grease, seawater, hot springs, and swimming pool.

 ❍ Semi-Precious Gemstones ❍

Usually, semi-precious gemstones do not require special care. If it gets stained, wipe with a soft moist cotton cloth and store it in a zipper bag after drying. Please be advised not to expose it to sunlight for a long time and avoid contact with perfume, alcohol, silver cleaner water, silver polish cream, and grease.
