Permanent jewelry is a custom-fit braclet, anklet, or necklace that's designed to be worn every day without ever taking it off. Instead of a clasp, the ends of the chain are safely welded together with a quick painless spark, creating a seamless durable piece that stays with you as long as you'd like.
It's called "permanent" because it's made to last and doesn't have a traditional closure, but it can always be removed by cutting the chain if needed.
