Pink tumbled stone, possibly rose quartz

Uncertain from the photo; possibly quartz (SiO₂), variety rose quartz

AI-generated identification · may be incorrect

Opaque, muted pink-lilac, with a smooth, rounded surface and faint linear markings. Quartz has Mohs hardness 7, a vitreous luster when freshly broken, and no cleavage; tumbling can make it look matte. The image does not show enough diagnostic detail to confirm quartz.

Physical properties

Formation & geological history

If quartz, it formed from silica-rich fluids in veins or pegmatites and is commonly Precambrian, though age depends on its source. The rounded shape suggests it may have been mechanically tumbled or water-worn.

Uses & applications

Tumbled quartz is used for jewelry, ornaments, and collecting; this piece appears decorative rather than gem-grade.

Geological facts

Tumbling smooths a stone without changing its geological identity. Pink color alone is not sufficient to distinguish rose quartz from other pink minerals or dyed material.

Field identification & locations

A scratch test and examination of a fresh surface would help identify it; quartz should scratch glass. The reported Northern Ireland area has varied geology, but this photo does not support a reliable local identification.
