A zwevel was a type of gemstone found in deeper sections of the oceans of Mon Calamari, a planet located in the Outer Rim Territories region of the galaxy. "Zwevel" was used by the Quarren, a sentient species native to Mon Calamari, as a first name for some members of the female sex.
Behind the scenes
The zwevel gemstones were first mentioned in the Galactic Campaign Guide, a 2003 sourcebook for Wizards of the Coast's Star Wars Roleplaying Game, written by Peter Schweighofer and J.D. Wiker. They were only described in a table of Quarren female names.
