Juwelen maintenance at GASSAN

  • We advise to maintain jewelery once a year. GASSAN own brand jewelery is serviced in our own workshop by our own skilled goldsmiths. The jewelry will receive the craft care they deserve during maintenance.
  • During this maintenance, the setting of the jewel is checked, the jewel is cleaned, polished and rhodium plated if necessary (with a new layer of white gold). This will make the jewel look like new again.
  • When purchasing a GASSAN jewel, you will receive the service to have your jewel cleaned annually and your setting will be checked free of charge, you do not have to make an appointment for this.
  • If the jewel is not our own brand and we cannot carry out maintenance for you, we will send your jewel to the aftersales of the relevant brand.
  • For questions you can always contact the Central Service Center and visit one of our locations with your jewel.

Tips: maintain your jewelry yourself

  • Have the setting of your diamond jewelery checked annually.
  • Do not expose your jewelery to chemicals, such as hair spray and perfume.
