chalcedony
This term describes a specific category of microcrystalline quartz characterized by a waxy luster and high durability. It is primarily used in mineralogical and gemological contexts to group various semi-precious stones that share a similar chemical structure but differ in color and banding.
Because it refers to a mineral substance, the word is treated as an uncountable mass noun. To refer to individual items made from the material or specific geological samples, speakers must use partitive constructions such as a piece of chalcedony or a specimen of chalcedony.
