The hook seems to be 925 which is silver, but can't see a stamp on the drop itself so I can't comment on that part. Silver ear wires are really no value to be honest, I make jewelry and buy them (925's) for pretty cheap in bulk. Best way to tell if it's real is to grab a magnet and if it clings to the magnet then it's not silver and most likely stainless steel. If it doesn't cling to it then it's silver. Hope that helps.
