If it's not an artifact of the photography, and the beads have turned more red with time, then that is one confirmation of phenolic resin.

If you have some household ammonia, wet a cotton swab with a tiny bit and rub a place that doesn't show. If the swab turns mustard yellow, that is also a good sign for phenolic resin.

I have been using "Bakelite" interchangeably with "phenolic resin" since many more people know this trade name and associate it with old plastic.
