Vintage, modernist sterling silver necklace, made in Mexico. This great necklace is a combination of plaques that are pierced with arrow shapes and holes, separated by spirals of silver. The chain consists of long bars with a narrow hook closure. It measures 17 inches long and is marked Mexico 925 TM20, which is a Taxco registration number. It is in excellent vintage condition, and at over an ounce of sterling silver, it has a nice heavy feel to it. It dates to post 1980.
