Here are some tips:

1. Remove jewelry before swimming and doing anything that might result in your jewelry coming in contact with water.

2. Remove jewelry before participating in acitivites that will cause you to perspire.

3. Perfumes, creams and moisturizers should be applied and well absorbed into your skin before putting on jewelry. Substances like oil and nail polish may also react badly to the metals, so avoid those while wearing your jewelry.

4. Avoid soaps and detergent, anything that is not pH neutral as that will tarnish your jewelry.

5. Jewelry should be the last thing you put on--and the first thing you take off. Take them off before you sleep!

For cleaning, use a soft cloth to wipe away any dust or dirt. Store your jewelry in sturdy storage to keep it away from direct light and dust.

We can provide services to fix your piece depending on availability. You would have to cover shipping costs.
