I have recently got a custom-made ring from a jeweler. It’s made from a byzantine-period bronze ring enveloped in a gold bangle. The bronze ring is “glued” onto the gold ring through some kind of resin, as far as he told me. Would bimetalism with rhe corrosion of the bronze ring happen? Thank you!
Moist air, rich in an electrolyte (salt particles) or human contact, providing both NaCl and H+ may supply the reagents needed for galvanic corrosion, with dissimilar metals in direct contact. This usually proceeds, albeit slowly, over time.
Note, exposure to fruit juices could be especially problematic, resulting in a matter of days of continuous contact in the presence of moisture and oxygen, in some visible signs of disfiguring pit corrosion.
Nevertheless, I recommend wearing the ring and enjoying it, but perhaps placing it in fresh distilled water (remove O2 exposure) at night after washing it with mildly alkaline soap (to clean off salts and neutralize body acids). If the vessel use is made of Aluminum, a very active anodic metal, the ring should do just fine.
