This is quite an appropriate topic for me at the mo. I have a Comoy meer and can't find any information on it at all, but I think it is a relatively contemporary pipe, maybe 70s/80s Turkish. I assumed that the stem was some synthetic/acrylic material made to look like cherry amber, but when I started cleaning up the button with 800 grit, I got a very strong scent of, what to me, smelled like tea tree oil. So I put it under UV and it fluoresced. Now I know most cherry amber is not naturally red but heat treated to achieve that colour, but since artificial amber/copal etc does not fluoresce, I have assumed it to be amber. The meer is excellent quality, completely flawless and whilst amber is very rarely used on modern pipes, I again assumed that this was a higher end pipe that used amber as a statement (as Peterson's have done I think).
None of this is particularly helpful to the OP, but from my research (which may not be correct of course), amber and copal both have scent of pine/eucalyptus, although the scent is slightly different (I think the surface needs to be abraded or heated first). However, under UV (365nm and less), copal does not fluoresce. When I was working on this, I tested out a few things on an very old broken stem that I did think was amber. This stem did not have any scent and when I did a hot needle test, I got a burnt plastic smell. Both stems once cleaned and buffed had no scent/taste I could detect and I have put a few bowls through the Comoy since and the stem felt very similar to Lucite and had no smell.
Sorry, a fairly incoherent post from me, but to address your question, amber does have a smell when heated or ground, as does copal. However copal does not fluoresce whereas amber does. I think it unlikely that any other synthetic stem material smells as such unless it is a compound made from tree sap that is not considered either copal or amber, but I don't know if any such material was used by pipe makers back then, but it is odd that it has a scent so strong that you can smell/taste it on a finished stem.
