| Material

Our products are made out of sterling silver (silver925) and K18.
We are proud to use precious metals that are entirely recyclable. Silver, with proper care, can be worn indefinitely, while gold remains an eternally valuable material, as evidenced by the ancient jewellery pieces displayed in museums worldwide.
As our designer has a metal allergy, therefore we can guarantee that OtanO keep our material in high quality.
However, if you get symptoms of metal allergy, please stop wearing and go to see a doctor immediately.  

| Care-guide

Please store your jewellery in the pouch provided and avoid hot water, cosmetics, perfume, chemicals, and sweat to increase the longevity of your piece.

​[ SILVER ]
Sterling silver is marked 925, which is 92.5% silver and 7.5% other alloys which makes jewellery harder, therefore it gets less damages. Silver can be tarnished by natural oils in skin and sulphur in knitwear, but a good clean with a silver polish cloth or silver dip will remove tarnish. We apply Rhodium coating or Silver coating on our silver jewels to keep longevity. 

[ VERMEIL ]​
We introduce Vermeil (18k gold over Sterling silver) for our gold items. Vermeil is very thick gold coating (-2.5microns), thus it keeps gold much longer than normal 18k coated item. Vermeil should not be polished. It should be dusted with a soft cloth, cleaned gently with warm soapy water, or immersed in silver dip for a short time.

We can not ensure how long the gold layer stays on, it very depends on your wearing behaviour.
We recommend you take off vermeil item when you do sports, cooking and taking a bath.

[ 18K ]​​
18K yellow gold is marked 750 it consists of 75% gold, the rest of the alloy is silver and copper. 18K yellow needs little polishing and although care should always be taken, they need little maintenance.
