Your coral looking plastic are similar to the Chinese classic but common cinnabar ones. These were popular in the '30's and copies flooded the market beginning in the 70's until today.

For themselves and others, the Chinese are well known for making very attractive, labor intensive, knock offs of their own beads from history. Even today, you can easily have anything copied in China.

And in the early 80's Kenneth Jay Lane realistically revived and popularized the 1920's -'30's "Oriental" look -but in gorgeous plastic. I recall in the late 70's, early 80's: intentionally walking past a Coral Gables, Miami, shop where it was advertised Kenneth Jay Lane was having a trunk show. By chance, he was standing in front of the shop. And I often wish I'd had the courage to say "hello." He looked at me and smiled. I kept walking.
