Hi Folks…
My vote is "synthetic" vs "simulated". They are NOT terms to be
used loosely. They are not interchangeable definitions of a stone.
It gets better depending upon how technical one wants to be…
Synthetic generally means man-made…In the world of it
usually refers to a man-made stone that has a natural counterpart,
which it shares general properties with i.e. synthetic ruby…
Then there are things like YAG*, etc., which do not have a
counterpart in the natural world, but are man-made simulants, and yet
by gem terminology are not a synthetic stone…
Finally there are general simulants, which can be anything that
looks like the natural stone, no matter what it is…glass,
plastic, whatever that mimics the natural stone…
So you have synthetics, which have essentially nature equivalent,
then man-made stones which do not exist in nature, so are only
simulants, but synthetics under normal usage of the term…And you
have natural stones which perform the function of simulants, and are
not synthetic at all…
Plus all the outright 'faux" stuff…
I think I got that right…[G]…

There may be some natural YAG somewheres…my favorite example used
to be CZ, but it was found in nature I forget when…
I wonder what a 1 carat natural CZ might be worth…if indeed
nature’s conditions even will allow for such a thing…
