Gamorrean coral, a type of coral from the Outer Rim planet Gamorr, was more common than both kyber crystals and Mustafar fire diamonds. During 40 BBY, jewel thieves Pax Maripher and Rahara Wick weighed the possibility of gathering Gamorrean coral on Gamorr for sale, but ultimately chose to pursue a rumored cache of kyber crystals on the moon of the Inner Rim planet Pijal in hopes of greater financial gain. Maripher later lamented his choice to forego the trip to Gamorr for its coral when they found the moon's deposit was actually made up of kohlen crystals instead of kyber.
Master & Apprentice, a 2019 novel penned by Claudia Gray, included a reference to Gamorrean coral.
