Dust, pollution, perfumes, and cosmetics can affect the surface of your pieces. This might affect the gloss, something that you certainly don't want to happen.
First, you should always apply perfume before wearing your pieces. Also, remember to remove them before taking a shower.
Try as much as possible to avoid exposing your jewelry to cleaners, hot water, and harsh chemicals. Ideally, you want to remove them before handling such solutions.
Substances, such as chlorine, can permanently damage the surface of your piece. Bear this in mind when using chlorine bleach or before diving in the pool.
When not using your pieces, remember to store them in an airtight container to prevent oxidation.
To clean your jewelry, use a clean cotton or microfiber cloth to buff it gently. Don't be tempted to use chemical cleaners as they can easily strip the finish.
Over time, the silver or gold layer is likely to tarnish. This is a common and natural property that adds a unique sense of character to the piece. Don't fret when that happens.
