Full Form Crystal Structures Instead of Just One Cell

These nine models, constructed of wooden beads and metal rods, include examples from three major crystal symmetry systems representing many key mineral forms in greater detail by showing more of their structure. Different atoms are represented by various bright colors. Each model is clearly labeled, and the set comes with an illustrated instruction booklet. Contents: Rhombohedral structure: calcite; hexagonal structure: graphite, magnesium, and wurtzite; cubic structure: carbon dioxide, cesium chloride, copper, diamond, and sodium chloride. Size: 7–15".
