Vintage Mexican Puffed Heart Link Necklace

This is a vintage articulated link necklace featuring a series of eighteen three-dimensional 'puffed' or repoussé hearts. The item appears to be crafted from sterling silver or a similar high-content silver alloy, consistent with 20th-century Mexican jewelry making. Each heart is uniform in size and bulbous in shape, joined together by small integrated metal loops that allow for flexibility and movement when worn on the neckline. The piece features a box-style clasp with a side thumb tab for securing the necklace. The metal exhibits a soft, aged luster with a visible pewter-toned patina, particularly in the recessed areas between the hearts and around the joints. There are minor surface scratches and micro-abrasions throughout, which are typical for vintage silver pieces of this age. Based on the construction and overall aesthetic, this necklace likely dates from the 1950s to the 1970s and is representative of Taxco-style craftsmanship. No maker's mark or fineness stamp is clearly visible in the top-down view, but these are typically found on the reverse side of the clasp or the back of the individual heart links. The craftsmanship shows good symmetry and sturdy link integration, suggesting a quality level above mass-produced contemporary costume jewelry.
