This is a fabulous vintage Mexican sterling necklace weighing in at 98.8 grams. Heavy but the woven links with bezel set turquoise beads makes this necklace very comfortable to wear. Measuring 16 inches around the neckline and just over 1 inch wide it lays flat and nicely. Signed on the slide in clasp; Echo en Mexico with the letters D F 925 Sterling around the initials TNC. This maker is listed in the Hougart book, but no information given. necklace is as found, I have not cleaned it. I leave that up to the next owner to decide if they would like to polish or not.
