Likely rough pink feldspar or rose quartz

Most likely microcline feldspar (KAlSi₃O₈) or rose quartz (SiO₂)

AI-generated identification · may be incorrect

The specimen is opaque pink-purple with a dull to slightly vitreous luster and irregular cleavage-like faces. Feldspar has Mohs hardness 6–6.5 and two cleavages near 90°; rose quartz is harder, about 7, and lacks obvious cleavage. Identification is uncertain from the image alone.

Physical properties

Formation & geological history

Pink feldspar commonly crystallizes in silica-rich granitic pegmatites during slow cooling of magma; rose quartz forms in hydrothermal veins and pegmatites. These minerals are generally Precambrian to Phanerozoic depending on the deposit.

Uses & applications

Used primarily as a collector specimen; feldspar is important in ceramics and glass, while rose quartz is used for carvings, beads, and inexpensive jewelry.

Geological facts

The small brown object appears to be a separate specimen, possibly tumbled jasper or quartz, rather than part of this sample.

Field identification & locations

Check for two flat cleavage directions and a white streak for feldspar; rose quartz shows conchoidal fracture and scratches glass. Common sources include Brazil, Madagascar, India, and U.S. pegmatites.
