Neerukivid

Neerukivid is a term used in some regional languages to refer to stones associated with water. There is no universally defined material called neerukivid in mainstream mineralogy; the name does not map to a single mineral species or chemical formula. The usage of neerukivid is localized and varies by dialect and community. Etymology is uncertain; the term is commonly interpreted as a compound relating to water and stone in languages where it appears, but there is no standardized derivation.

In practice, neerukivid may denote a range of hydrous or water-worn materials. In riverine contexts, it is often used to describe smooth river pebbles formed from various parent rocks. In other settings, it may refer to mineral-rich nodules found near springs, or to decorative stones with a water-worn appearance. The stones may be employed in construction, landscaping, jewelry, or ceremonial objects depending on local tradition.

Geologically, neerukivid does not indicate a single mineral group; the stones can include quartzite, chert, calcite, or other lithologies that have been rounded and altered by water. Because the term is non-specific, reliable identification requires direct petrographic or chemical analysis.
