Every ring from BISAKU
comes with free lifelong cleaning

As part of the lifetime service, we will clean your rings free of charge with ultrasound, which will remove surface dirt, clean the deposits around the stones and, thanks to this, the rings will shine beautifully. We will also check the fit of the stones.

If you give the rings the care they deserve, they will sparkle on your hands for a long time without the need for cleaning or renovation.

If you need it, you can also use a complete professional service. This service includes restoration of surface finishes (polishing, matting,...), restoration of the rhodium layer on white gold rings, as well as removal of impurities from around the stones. This service is already charged and we do not recommend it to be performed more often than once every five years in order to avoid excessive loss of material.
