Polished/polished rough quartz crystal, likely hematoid or included quartz

Quartz (SiO₂), with probable iron-oxide inclusions; possibly smoky or rose-tinted quartz

AI-generated identification · may be incorrect

Translucent gray-brown to pink-orange body with vitreous luster, conchoidal fracture, and partial crystal faces. Mohs hardness 7; hexagonal crystal structure; no cleavage; specific gravity about 2.65. Strong lighting and surface wear make exact color assessment uncertain.

AI Estimated Value

About $5–$30 for a small common polished/included quartz specimen; $30–$100+ if provenance, inclusions, or crystal form is unusually attractive.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich hydrothermal fluids in cavities, veins, and pegmatites; red-brown inclusions are commonly hematite or limonite. Quartz ranges from Precambrian to modern geological settings and cannot be age-dated from this photograph.

Uses & applications

Used for jewelry, carvings, lapidary pieces, countertops, glass, electronics, and industrial abrasives. This small included specimen has modest decorative and collector interest.

Geological facts

The translucent zones and angular crystal geometry distinguish quartz from ordinary glass. Iron oxides can produce red, orange, brown, or black internal patches.

Field identification & locations

Look for glassy luster, hardness sufficient to scratch ordinary glass, lack of cleavage, and curved fracture surfaces; avoid relying on a scratch test if the piece is valuable. Common worldwide in hydrothermal veins, geodes, and pegmatites.
