While we do our best to provide you with a secure and high quality piece, the jewelry is designed to break under pressure. All of our chains are tested in house and will break with 10lbs of pressure or less. This is for your safety. If you find your bracelet is breaking frequently, permanent jewelry may not be suitable for your lifestyle. We will be happy to add a clasp so that you can still wear your custom fit high quality jewelry. If your permanent bracelet (or necklace, anklet etc) breaks along the chain a second jump ring will be added.
