We have discussed quartz crystals which despite their high Q, may suffer from periodic "jumps" in frequency do to what I assume are imperfection that hardly affect Q. If they did affect Q, then that would have been a good way to grade them for this behavior.
Temperature coefficient is also independent of Q. If I built a pendulum out of a material with a high thermal coefficient of expansion, it will not be very stable but the Q will be unaffected.
