Berylin

Berylin is a name that appears in several unrelated contexts, but it is not a widely recognized substance in scientific literature. No peer-reviewed chemistry or mineral databases establish a standard formula, structure, or occurrence for berylin. Because of this, descriptions of berylin vary and often depend on the source using the term.

In fiction and popular media, berylin is often described as a rare crystalline material with exceptional properties, such as high hardness, low density, or unusual energy behavior. Specifications—when provided—are invented by authors and do not reflect real-world materials.

Etymology: The term appears to be a neologism derived from beryl or beryllium, following common naming conventions for minerals and advanced materials. However, without a formal definition, any such origin remains speculative.
