Vintage Triple Strand Necklace with Aquamarine, Mother of Pearl, and Rose Quartz

This beautiful and unique vintage necklace consists of 3 strands of what I believe are natural stones and crystals, however they have not been professionally tested. Please see photos for details. The necklace is very well made and unmarked.Beads are strung on wire, sturdy toggle clasp closure, and jump rings are all soldered. Detailed information within the description is based on my own research and what I believe these strands to consist of. All measurements are approximate and accurate within my ability, however each bead has its own unique features and sizes/colors vary slightly from each. I buy & sell estate jewelry, much of what is vintage or antique. There is some minor wear from prior use but nothing that significantly takes away from the overall look. Cleaning will be left to the buyer's discretion.
