Permanent jewelry is a new service that refers to a piece of high quality jewelry (usually a necklace, ring, anklet or bracelet) that’s welded together instead of secured with a clasp. 

Since it is "permanent" there's no chance of you ever losing it. You don't have to worry about fumbling around one handed trying to get your bracelet on. Plus, its claspless so no more getting annoyed with your necklace clasps moving forward.
