hi all, as I’ve previously posted I’m buying a Tiffany locket, however I’m very worried about the durability of the thin chains Tiffany offer. The chain the locket comes with as a set only weighs about a gram and looks very Fragile. They also offer a slightly thicker chain weighing in at 3 grams but still this doesn’t look all that durable... I have young children so this is quite a big concern. Does anyone have any experience with these chains and having issues with them breaking? Will be purchasing in 18ct yellow or rose gold
