Enhancement jewel

From Wookieepedia, the Star Wars wiki.

Enhancement jewels were used in high resolution projection systems. They were spherical, and were used in conjunction with a focusing lens. The Wookiee Jedi Lowbacca used such a jewel as a lightsaber crystal in his lightsaber, scavenging one from components left by Rebel technicians in the Great Temple on Yavin IV.
