Azure Malachite Beaded Necklace

blue and turquoise coloured beads in a unique bead shape. from what I understand, thr stone is reconstituted out of stone and permeated with resin to reconstitute it and give the interesting patterns you see. the silver tone beads between, seem to have loss of shine/degrading. necklace has been sitting in a drawer, never worn. necklace is about 28 inches long
