I have been wondering why there are random-seeming holes in some types of carved Chinese beads that are not terribly old: see the example below. Do they serve as datum or set points for carving machinery? Can someone enlighten me? Thanks!

Also, the price of these carved rose cherry resin beads seems to have taken quite a downturn in the last few years!

      - Rub a barely wet (with ammonia) q-tip on a smooth area. Will turn mustard yellow if phenolic. (no text) --- Rosanna ( 2019-09-06 14:27 )

        Avoid washing with anything harsh like 409. --- Rosanna ( 2019-09-06 23:26 )
      - Your results indicate that it’s a plastic other than phenolic resin, or maybe real amber --- Rosanna ( 2019-09-06 23:18 )

    - These are 1930s phenolic plastic, carved in China—often sold as "cherry amber." (no text) --- Beadman ( 2019-09-06 07:18 )
    - There is more dark amber undertone to these beads --- Rosanna ( 2019-09-06 15:40 )

I suppose the shallow concavities are just decorations (!). (no text) --- Beadman ( 2019-09-06 05:56 )
Beadman, I think you are right --- jrj ( 2019-09-06 06:14 )
