Hello s3034585
When you make a project that contains a crystal first of all you are looking at the frequency, temperature drift, and aging, So the first you have to look is the frequency of the crystal second if the project demands accuracy then you have to see the temperature and time drift. At last a crystal by itself can't do oscillations you have to put 2 capasitors which there value it depends from the manufacturer and the crystal frequency. I hope my opinion would be helpful for you.
