Your jewelry is made of glass, so it is highly recommended that you remove your jewelry over a soft surface such as a bed or carpet. The dichroic will not fade or wear off. Pendant bails are made of Sterling Silver plated zinc and nickel free. The only thing that could harm the glass is by scraping or dropping it onto a hard surface. The glass will be preserved for years to come!
As with any metal, over time, it can oxidize. If you expose your pendant bail to excessive perspiration, the plating could wear off the bail part. Please remove your pendant during any type of exercising or sports. You may apply a mild cleaner with a cotton swab and then rinse. Do not use a harsh cleaner on the bail. Use a rubbing cloth if needed. I have been fusing glass for over 6 years now and my very first pieces look just like my favorites today.
