Physical properties

Formation & geological history

Formed by the slow crystallization of silica-rich magma beneath the Earth's surface. This specimen appears to be water-worn, likely from a river or glacial deposit.

Uses & applications

Construction, countertops, monuments, paving stones, and landscaping. Polished varieties are highly valued for architectural facades.

Geological facts

Granite makes up a large portion of the Earth's continental crust. The pink color is specifically due to a high concentration of potassium feldspar (orthoclase).

Field identification & locations

Identify by its interlocking crystalline texture and pink/salmon color. It is commonly found in mountainous regions or glacial till. Collectors look for unique large crystal patterns or mineral inclusions.

Dark Igneous Rock (Likely Basalt or Diabase)

Basalt (extrusive igneous rock) or Diabase (intrusive igneous rock - also known as Dolerite), largely composed of plagioclase feldspar, pyroxene (augite), and sometimes olivine and amphibole. Exact mineralogy would require thin section analysis.
