Orange carnelian (likely)

Chalcedony, microcrystalline quartz (SiO₂), colored by iron oxides

AI-generated identification · may be incorrect

Small, rough orange-red fragment with a waxy to dull luster; quartz’s trigonal crystal structure is microscopic, with no visible cleavage. Hardness 6.5–7 Mohs; specific gravity about 2.6.

Physical properties

Small, rough orange-red fragment with a waxy to dull luster; quartz’s trigonal crystal structure is microscopic, with no visible cleavage. Hardness 6.5–7 Mohs; specific gravity about 2.6.

Formation & geological history

Forms when silica-rich fluids deposit chalcedony in rock cavities and veins; iron impurities produce orange-red color. Its age and precise geological source cannot be determined from the image.

Uses & applications

Carnelian is used for beads, cabochons, carvings, and ornamental objects; this tiny rough piece has little practical or jewelry value unless cuttable.

Geological facts

Carnelian is an orange variety of chalcedony, rather than a distinct mineral species.

Field identification & locations

Look for translucent orange-red color, waxy luster, and hardness near 7; common sources include India, Brazil, Uruguay, and Madagascar. The image alone cannot confirm it—orange glass or another material may look similar.
