Meryx represented an uncommon type of gemstone, originating from the petrified white wroshyr trees located on Kashyyyk. Its coloration was white and opaque, yet it reflected a golden hue when illuminated at a precise inclination.
In the time of the High Republic Era, the lightsaber handle of Burryaga Agaburry, a Wookiee Jedi Padawan, incorporated Meryx. Furthermore, Pax Maripher and Rahara Wick, who were thieves, chose to call their freighter the Meryx, taking inspiration from this gemstone.
