A nice vintage Tuareg necklace from the Niger. The pendant is an amulet, made of mixed metals, and usually carrying some kind of protective incantation. The chain is strung black glass and four tube beads. It closes with a hook and eye mechanism Dimensions: Length of pendant 4 cm (1 1/2") Width of pendant 3 cm (1 1/8") Chain is 48 cm (19") long Weight is 23.4 g. Tuareg jewelry has distinctive styles that make it immediately recognizable. The geometric striations are significant, but have been lost with time. I remember reading once that every line made in the metal means something specific.
