Can anyone tell me what this is. The ends have male/female screw connectors and it is 5" long. Solid Sterling silver. I have 2 of them. As a bracelet it would be tricky to attach and screw together because it will twist. No sure if it is some type of extension. It has a Judith Ripka look to it, but is not hallmarked. I know ESPO/SIG has some designs that snap into a enhancer. Never had one that screwed together.
