here is my experience…with Rio chains
i selected the Rio sterling silver 1.1mm cable chains (and 1.5mm) for their delicate, fine nature. I have used them for many years and have been notified by customers of broken chains fewer than 10 times. (actual total broken chains unknown)
when i first started using these chains, as a test, i wore one of the chains, with a pendant, for over a year without taking it off, and it held up well.
My only disappointment was when they upgraded from a spring ring clasp to a tiny lobster clasp, which i found difficult to open due to its shape and size.
Rio’ s great customer service resolved this for me by allowing me to special order bulk chains with the spring ring that i prefer.
i am really amazed at how shiny and bright and tarnish resistant these chains remain while in inventory.
On another note: I recall discussing chain manufacturing with someone…i forget who…who said that these type of fine chains were made with solder-filled wire(?)…with chain making machines, and then soldered closed with heat(?)…is this correct?
