This is a double strand circa 1940s Mexican sterling silver graduated beads necklace. The 2 strands measure 15" and 16" long and are joined by a marked clasp. The clasp is marked HECHO EN MEXICO TAM and IGUALA 925. Iguala is the city in Mexico and I assume Tam is the maker.
This necklace weighs 24.5 gr. The beads are hollow so it is relatively light weight. The beads range in size from 5mm to 10mm.
Condition: A few of the beads have minor indentations. There is expected patina due to age.
This is a classic silver bead necklace.
