Quartz, Rock Crystal Specimen (Mineral)
A quartz (rock crystal) sample, about 1 inch (3 cm). One of Earth's most abundant minerals, quartz is built from a tightly packed framework of silica tetrahedra, giving it a fairly high hardness of 7, no cleavage at all and a distinct euhedral crystal habit that makes it ideal for collections. It suits lessons on hardness, lustre and fracture and classroom identification labs, aligned with NGSS evidence statements. Supplied in a clear, labelled, barcoded bag.
