[Star Wars] If a fully trained Jedi lost their saber and required a placement, would they have to go through the crystal finding process all over again or did the Jedi have spare crystals lying around in a drawer somewhere for just such an occasion?

It would seem that there are some spare sabers kept ready just in case (*see Anakin and Obi-Wan getting sabers from their Jedi rescuers in the Geonosis arena*). However, this may be extraordinary circumstances and there might not always be spare sabers.

While it would seem more efficient for the Jedi to simply have a stock of kyber crystals for those who'd lost theirs, you're forgetting that the search for the lightsaber crystal is as much ritual as it is practical, and the Jedi don't exactly seem like they would exploit a world to harvest all of its kyber crystal veins.
