Vintage necklace

Lovely vintage 90’s necklace. Missing one rhinestone that’s not noticeable when wearing. Butterscotch like plastic I think is lucite? There is a small indentation on the larger plastic and I think happened when it was made because it’s very smooth. Also not noticeable. Could use a gentle polishing up. Please see photos for better description. Thank you. Measures approx 30” in total length.
