22” jadeite and glass bead/genuine pearls necklace

Necklace is in good wearable condition although a two of the darker purple beads have wear. You can feel that they have a rough spot and we’re possibly dropped. It’s not something that’s obvious or visible when wearing. It’s upon examining them. Necklace is kept in a clean smoke free home. My presidium II gem tester says the beads are jadeite/spinel. That’s the category it gives me. Researching the difference with the two I’d guess to say jadeite. Not all are stones though. The 6-7 mm genuine Pearl ( verified by gemologist), small 2 mm black separating beads and 8 mm green beads are glass. So the purples, pinks, and clears are jadeite and approximate 10- 11 mm round. Toggle clasp is 500 silver so not quite 925 but does contain silver. 22” #naturalstone #jadeite
