I know this is not what you ask for, but I have had good experience with 
mounting in capillaries (borosilicate, a bit stronger than quartz, but quartz 
should work also if you are very careful), leaving the crystals in the mother 
liquid, to fly them over by FEDex from USA to Europe. Leave the capillaries at 
the longest length possible, so that someone at the synchrotron can open the 
capillary and push the crystal out of the liquid and close again the capillary, 
or even push the crystal out and remount the crystal in a different way. For 
the flights, I left the cappilaries pending a little loosely in the air, with 
their ends stuck into cotton balls, into a smaller box, that on its turn was 
fixed shock-damping stuff into a strong, uncrushable box. Cheap, quick and 
easy!
