Hello, just back in the office again and I don't think there is any way the chain will fit. Although the loop of the scorpion pendant is apx 8mm long and the width is about 4mm at it's widest, to get a chain to comfortably fit, I would allow a few mm. So sadly no, a 9mm chain would not fit it. Sorry we couldn't help much. Kind regards Simon https://www.maldonjewellery.net/search?controller=search&orderby=position&orderway=desc&search_query=scorpion&submit_search= We do have other silver scorpion charms but as they are charms they are much smaller and would look lost on such a chain, added to the fact the loops would be much smaller too.
