I have a gold one. It still looks like new, mostly because I stopped wearing it about 3 months after the wedding in 1975.
Working with machines and electrical equipment, a ring can be quite dangerous.
A motorcycle or car battery has enough energy to make any finger ring cherry red. Then when you feel that painful searing heat, you violently withdraw your hand, effectively removing the skin from your finger from the band's position to tip.
Dangley jewelery can also find a bridge position between power busses, drawing high current, as well as getting caught up in rotating equipment.
Cheers,
