New vintage Dainty Amber swirl earrings

New vintage Dainty Amber swirl earrings Gold plate dainty swirl design. C. 1980s. New Nwot. On original placard. Surgical posts. This amber shows visible inclusions. The same manufacturer supplied genuine B.C. Jade, Rhodonite, Hematite, Paua shell. I’m just not sure if the amber and amethyst are natural or synthetic “lab” gems. I paid the premium price so I tend to think they are good quality at least!
