Raw Gabbro Igneous Rock Hand Sample, Approx 3 inch

This raw gabbro specimen is an igneous rock formed within deep magma chambers where iron-rich melt cools slowly, allowing olivine and plagioclase feldspar to crystallize. It serves as an excellent example of phaneritic mafic rock for identification and classification exercises. This hand sample measures approximately 3" and is selected and processed by a geologist to ensure it exhibits defining features of gabbro. The specimen is individually packaged in a transparent bag with labeling and barcoding for easy identification. Sourced from locations worldwide and processed by hand in Victor, NY.
