What are these sets of pool balls?

I have two sets of balls that came with my anniversary table. Can anyone tell me what they are? Theres no logos or words anywhere on any of them. The numbers feel deeply part of the ball if that makes sense? Any help would be great!

Looks like a set or Aramith standards on the left and a set of Aramith premiers on the right.

I thought that Aramith balls had a logo on them?
