Multi Strand Genuine Mother of Pearl MOP Pendant on Brown Glass Beaded Necklace MOP Button Clasp 16" beaded necklace made from 3 strands of glass brown beads. There is a wood bead where the pendant Mother of Pearl Rectangle is attached. Mother of Pearl Rectangle measures about 2 1/4" long by 1" wide. The MOP piece is pretty on either side, and in my opinion makes the necklace reversible. The color of the brown beads are a bit red in the photos. It's more of a milk chocolate brown color. It with go with a lot of different color tops.
