Gemstone 25” white & pink necklace jewelry

Necklace is in good condition and kept in a clean smoke free home. One bead is loose. It can be pressed back in place or removed without effecting the use of the necklace. It’s a white bead shown in photos. I see mother of pearl but the pink beads I am not sure. They could be quartz. The gold plating I am not sure either. I do not know the metal used and did not find markings, brand unknown. Necklace measures 25”, gold tone screw-back clasp, 4mm pink beads, 2mm white beads, 2mm gold tone beads, and 8mm X 4mm mother of pearl beads. #necklace #jewelry #gemstone #motherifpearl #mother-of-pearl
