[A few of the pictures cast a slight golden hue, but the necklace is unquestionably silver-colored (sterling silver.)] Vintage sterling silver necklace. I've seen it described as a gate link. Approx. 17" end-to-end with open clasp; subtract about .75" with clasp closed. Described as "modernist" in other people's online listings. You can lie it flat and it is collar length. Maker's mark: TM 153. Stamped Mexico 925. According to my scale, an Accuteck, the piece weighs 54 grams. (The manual said the scale came calibrated. I don't know if there is a margin of error.) Lightly cleaned. Very good vintage condition. I saw slight irregularities on a few of the gate links, which I attribute to the lovely imperfections of a hand-made jewelry piece. I have seen another listing showing this as unisex, but I think it's more for women. I am not planning any more price reductions. Please review the photos and let me know if you have questions or would like more photographs.
