PeteC, I do have a vibratory tumbler.

I may give it a try, but I afraid to damage the delicate
cubes.

That will depend entirely on the media you use
and the time you're willing to devote to the
process given the machinery deployed.
But if you need to get deep milling marks out,
you can count on angle sharpness suffering in
the indiscriminacy of the process.

I looked for Turner's cubes on eBay once and
only saw some cheesy plastics. You might
try a metal with an apparent color turn away
from aluminum, say bronze/brass, to gauge
differential customer interest.

A nice historical blurb on the history of the cubes
and their significance in evaluating a machinists
skills would be good alongside some nice
poetic quote about "world's within worlds",
"atoms within mass", "geometric projection", etcetera.
Punchy lines are great but the copywriter's guide is
that interested clients will read all they find interesting.
Your descriptive powers will not have insignificant
result. If you ever read the blurbs accompanying the
"pet rock" phenomenon, there's proof.
