  Diodes occur naturally, all you need to do is find them! Good places to look for them are conductors and crystals. https://en.wikipedia.org/wiki/Crystal_detector https://en.wikipedia.org/wiki/Crystal_detector https://rimstar.org/science_electronics_projects/razor_blade_diode_for_crystal_foxhole_radio.htm https://rimstar.org/science_electronics_projects/razor_blade... Good luck! And don't sneeze once you've found a good spot.
