Our Unique Stainless Steel Half Persian Chain Necklace in 18 inches takes 252 rings and 2 hours to construct! The odd way the rings overlap each other, forms their pyramid shape. Making this weave quite difficult to get started. Once it gets going though, the little pyramids begin to stack onto themselves and hold their shape. The stainless steel wire used in this size is slightly matte, which makes for a nice soft look. This weave is in a class of its own! 6.7 mm wide, ending in a Hand Forged 'S' Clasp.
