The make of each jewellery vary depending on the product and design. Please refer to each individual descriptions for detail. Most of Open Project's jewellery consist of gold plated or fine gold plated sterling silver. 
Please avoid contact with liquids and creams when wearing your gold plated jewellery.  Substances such as chlorine, perfume, etc may discolour or damage your jewellery, leave residue, or cause it to tarnish rapidly.  Store your gold filled or gold plated only when dry. Keeping your gold filled or gold plated jewellery as dry as possible will extend the life of its colour and louster.  For alloy based jewellery, please note that excessive sweat could lead to discolouration. We would highly recommend wiping your jewellery after wear. 
To clean your jewellery, you may use a cotton ball or a soft cloth to wipe off residue and dirt.  Other tools such as soft headed toothbrush and some mild soap maybe used to wash your jewellery. Rinse thoroughly with lukewarm water, then dry quickly.  Do not let your jewellery remain wet in the open air.  Make sure your jewellery is completely dry before putting it away for storage.
