OtanO Polishing Cloth

 

| Material

Our products are crafted from sterling silver (925) and 18K gold. We proudly use precious metals that are fully recyclable. With proper care, silver can be worn indefinitely, while gold remains eternally valuable—as evidenced by ancient jewellery pieces preserved in museums worldwide.

As our designer has a metal allergy, we are committed to using only high-quality materials. However, if you experience any symptoms of a metal allergy, please stop wearing the item immediately and consult a doctor.

| Care-guide

Please store your jewellery in the provided pouch and avoid exposure to hot water, cosmetics, perfume, chemicals, and sweat to maximise its longevity.

[ SILVER ]

Sterling silver is marked "925," meaning it is 92.5% pure silver alloyed with 7.5% other metals for added durability and resistance to damage. Silver can tarnish due to natural skin oils or sulfur in knitwear, but tarnish can be easily removed with a silver polishing cloth or silver dip solution. We apply rhodium plating or additional silver coating to enhance longevity and prevent tarnishing.

[ 18K/24K coating ]

Our gold items feature thick gold plating (1 micron or more) over sterling silver for superior durability compared to standard plating. Gold-plated items should not be polished aggressively. Instead, gently dust with a soft cloth, clean with warm soapy water, or briefly immerse in a silver dip. The longevity of the gold layer depends on your wearing habits—we cannot guarantee an exact duration. We recommend removing gold-plated items during sports, cooking, bathing, or any activity involving moisture or chemicals.

[ 18K ]

18K yellow gold is marked "750" and consists of 75% pure gold alloyed with silver and copper. It requires minimal maintenance and only occasional gentle polishing. With proper care, it remains beautiful for a lifetime.
