The lightsaber of Jaina Solo was a weapon that Jaina Solo assembled during her teenage years at the Jedi academy located on Yavin 4 in the year 23 ABY.
When Jaina was thirteen years old, she started her training at the Jedi Praxeum run by her uncle. As part of her training, she and her classmates each built their own lightsabers, incorporating synth crystals to generate a purple-colored blade.
