Black mother of pearl eyeglass chain made with stainless steel 49 strand beading wire (the best), heavy wall sterling silver crimp beads, wire guards, split rings & lobster clasps. The wire, wire guards, split rings & lobster clasps are all stainless steel so they don’t tarnish even in the most humid or tropical environments & they add to the durability of the chain. The wire guards protect the wire from wear. The stainless steel components add to the cost of the chain but they will keep your hard working chain in good shape. The lobster clasps let you change out the end pieces & you can turn your eyeglass chain into a necklace then back into an eyeglass chain again. Mother of pearl tends to have a calming effect on those that wear it, reducing stress. This allows for better memory recall. This light weight chain is approximately 28 long, made to last & is truly a necklace for your eyeglasses or sunglasses.
