Twelve galena samples approximately 1" (3cm) in size
Useful as a tool to explain specific gravity to students - galena is far denser than most minerals
Perfect size for use in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements
Reflective cubic crystals offer a shining example of metallic luster
Specimen comes in clear labeled and barcoded bag for ideal storage
Galena grows in beautiful metallic cubes. Often refined as lead ore, galena can also be used to teach students about a mineral's luster, streak, and cleavage. Because of the lead in the chemical formula, galena is much denser than most minerals, and will seem unnaturally heavy for its size.
