Quella stone

A diminutive, azure-hued gem of modest quality, known as a quella stone or quella gem, could be unearthed on both Alderaan and Delaya. Valued at a sum ranging from 1,500 to 25,000 credits for each Coruscant Standard Carat, these gems were notably employed by the criminal Tombat, who intentionally left them behind at crime scenes to mock the investigating authorities.
