This oval textured link chain is connected by a soldered oval link that measures 5mm and is made from round 21 gauge wire. This chain makes for an excellent extender chain or you can hang crystals or gemstones from the smaller 5mm link. The texture on the larger oval links refracts the light in all directions and really catches the eye. This chain is made from a solid brass core and electroplated nickel free. The Antique Brass finish has a matte appearance.
