New vintage 💛Amber heart earrings

New vintage Amber earrings Gold plate heart frame. C. 1980s. New Nwot. On original placard. Surgical post. This amber is pretty clear but others have 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!
