Yes, most silver rings can be resized by professional jewelers, typically within a range of about two sizes up or down. The process involves either adding metal to increase size or removing a section to decrease it, then soldering and refinishing the ring. However, there are limitations—rings with extensive engraving, certain settings, or special design elements might be difficult to alter without affecting their appearance. Eternity bands with stones all around can't be traditionally resized. The cost varies depending on complexity, but silver resizing is generally more affordable than gold. For meaningful pieces that don't fit properly, professional resizing is worth the investment to ensure both comfort and longevity.
