Compared with other items, the gold plated or silver plated jewelry bead, which is made by covering a base metal a very thin layer of gold/silver, is more reactive. So it is necessary to protect the gold/silver plated jewelry beads from damaged. You could refer to the following tips to take care of your jewelry beads:  

• Firstly, please be sure to keep silver plated/gold plated items from water, soaps, and perfumes. Take off your jewelry before washing or have a bathe.
• Secondly, keep it away from hard surface, even a light scratch will cause the layer to wear away fast
• Thirdly, clean it gently with soft cloth or the appointed jewelry cleaner, this could help to eliminate any dirt or dust which will wear away the layer on the jewelry surface.
• If your jewelry is not wearing, store it in a dry place or wrap with soft material.

I hope this is going to help you.

Kind Regards
