Are you sure they are carved and not molded?

Have you tried the reamer or Simichrome tests?

Rub a barely wet (with ammonia) q-tip on a smooth area. Will turn mustard yellow if phenolic.

Avoid washing with anything harsh like 409.

Your results indicate that it’s a plastic other than phenolic resin, or maybe real amber

These are 1930s phenolic plastic, carved in China—often sold as "cherry amber."
