Abstract
Internal growth and dissolution features are visual characteristics of some natural, synthetic, and treated gem materials. Open channels or need-like structures are occasionally observed in natural diamond, synthetic moissanite (SiC-6H), and chemically-etched synthetic colorless quartz. The distinguishing features among the channel structures in these materials are compared, and possible formation mechanisms of the channels associated with dislocations or dislocation bundles are discussed.
