Physical properties

Hardness: 6-7 (Mohs scale); Color: Tan, brown, reddish-pink due to iron oxides; Luster: Dull/Earthy (matrix), Vitreous (quartz veins); Structure: Clastic/Granular; Cleavage: None.

Formation & geological history

Formed through the accumulation and cementation of sand-sized mineral or rock particles. The visible white crystalline bands represent secondary quartz veins formed by hydrothermal fluids filling fractures long after the initial sedimentation.

Uses & applications

Common sandstone is used in construction and landscaping. Specimens with interesting veining or colors are used for lapidary work or as garden accents and decorative desk pieces.

Geological facts

Sandstone can withstand weathering for centuries and is the most common rock used in the construction of ancient temples and cathedrals worldwide.

Field identification & locations

Identify by its gritty, abrasive texture (like sandpaper) and visible quartz grains. Often found in desert environments, riverbeds, and coastal cliffs. Collectors look for high-contrast 'Liesegang bands' or mineralization.
