Aquamarine glass choker pendant necklace Japanese

The round beads measure various sizes between 10mm & 5mm, & were made in Japan during the 1940’s. They're a very pretty translucent aquamarine blue. The teardrop-shaped pendants measure 13mm by 9mm, & are an aquamarine colored glass with black textured dots. The rolo chain, head and eye pins, jump ring, and lobster clasp are gunmetal colored, and are NOT vintage.
