They are very cute. Not sure about hand made, I already got them made that way. I didn't see any 14kt stamp on the wires, I only go by what says on the padding they came on. I was told that gold wires are not stamped. Also took to local jewerly store, and they did some kind of test (liquid-chemical) and it held 14kt. So... I hope it will answer all other questions bidders might have. About shipping to Australia? Never done international, don't know how much it would cost to ship it. If anyone can tell me, then I will see if able to. Hope it answers your question
