I know many collectors,
who prefer thicker slices, to have a little more an impression of the
exterior of the stone,
..and in fact, whenever they could afford, they will choose endcuts,
because there you have something in the hand, you see how the stone
originally looked from outside

and - especially compared to ultrathin slices - an endcut is made for
eternity.

And there are the problems, if you cut a stone slice too thin, you can't
grind and polish it anymore.
Perhaps you know these wire cut ultrathin stone slices, they have a huge
surface/weight-ration but often they have that wavy relief from cutting,
which you can't remove anymore, because the slice would break into pieces,
if you'd try to grind it.
 
And if you have a too thin iron slice and you'll get problems with rust, it
will be extremely difficult, if not impossible, to refinish and to re-etch
it.

Nja well, Mike, from which thickness/cut loss on a slice becomes more
expensive per weight,
that is in practice alone the problem of the preparator :-) - because in the
end the collector decides, whether he would be willing to pay a higher price
per gram. (And I tell you, most won't).

Best!
Martin
