About Black Onyx Connecter in Gold Filled for Permanent Jewelry 4mm 14k Gold Fill
This 4MM connector is made from 14k gold fill. A synthetic, waterproof deep black onyx stone is set in the center. The connector has a flat back to easily sit on the wrist or anklet during the permanent jewelry process. Measuring in at 4mm in overall diameter, it is dainty enough to work with chain up to 3mm in width. The jump rings on either side are closed, they can be looped through a connecting jump ring which then attaches to the chain when used with any permanent jewelry welder or pulse arc welder. Make sure to use argon to prevent oxidation (black spots) and a red fiberglass brush to remove any additional burn marks.
