This is truly a gorgeous African AMAZONITE necklace.      We purchased it in Morocco but most likely the beads are from Mauritania.     The beads go from small to large, from 1,2 cm (0.5") up to 2,2 cm (0.88").    There are 42 of these wonderful unpolished round Amazonite beads in this necklace, each with a little silver / metal bead in between.     Length of the necklace is 48 cm (19"), weight is 160 grams.      499 Euro.
