Quartz is a well known mineral to geologists and the general public by virtue of its common use in jewelry. On one hand, geologists know it as the second most abundant mineral present in the Earth’s crust-beaten only by feldspar. A geologist might also describe it as composed primarily of silica, or they might simply label it as a seven on the Mohs scale of hardness. But all of these properties are generally lost to the public. Instead, the public knows quartz as the main component of many reasonably priced jewelry sets.
Perfect for necklaces, earrings, or bracelets, quartz comes in a variety of colors. There is one common form of quartz, which is clear, but it also appears in purple (amethyst), yellow (citrine), milky white, and many more varieties. Another common and popular form is rose quartz, which is pink in color and most often seen in a rose quartz necklace or rose quartz figurine. No matter which color of quartz you find most appealing, the mineral always offers jewelry and other items an element of beauty.
