Offered for your consideration is an unusual link chain in good size. It has a spring clasp which works well and is 18" long and weighs 4.5 grams. The chain is @ 2.5 mm wide and is hallmarked 585 for 14K.
It is in excellent estate condition. I am always on the look out for unusual vintage chains to marry with my many quality pendants. This one might fill that need for you.
