This stunning array gives you a glimpse of the Earth's incredible palette of mineral colors. Some minerals always come in the same color. For example, malachite is always green, rhodochrosite a shade of pink or red. Others, such as quartz, are normally colorless but boast a rainbow of hues if they contain impurities, inclusions, or defects in their atomic structures.
