threestones

Threestones is a polysemous term used to describe triadic arrangements of stones that appear across geology, archaeology, and fiction. The concept centers on sets of three stones rather than single specimens, and it is used to denote both natural formations and man-made objects.

In geological contexts, threestones refers to clusters or alignments where three stones occur in close proximity, often within a single geode, bed, or rock fracture. The stones may have similar or related mineral compositions and are sometimes studied for insights into local formation processes and rock history.

In archaeology and ethnography, threestones describe ritual artifacts or markers consisting of three stones arranged in a triangle or bound together. Such objects appear in many cultures and are frequently linked to calendrical cycles, oaths, or consecration practices, with symbolism tied to triads such as past, present, and future.

In modern culture and fantasy literature, threestones are often depicted as magical or symbolic objects—gems or talismans that gain power through triadic alignment or triple inscriptions. The term, therefore, serves as a flexible category for discussing three-stone phenomena without prescribing a single material class or use.
