Q: I am trying to understand the difference of quality and longevity when using gold plated or gold filled clasps; also silver, or nickel. I think there must be many versions of gold plated as some tend to wear off immediately and others last. I am not making expensive pieces yet but I would like to use good quality clasps that last. What do you recommend and how do I recognize good from bad. I live in China and feel very unsure even when they tell me its good; price is not always the indicator!
