Avg Size Range: (1 to 2 Inches Long) Sizes Vary Quartz is one of the most common minerals found in the Earth's crust, and takes on a variety of colors depending on the other minerals and trace elements that are included as it forms and grows. These pieces are formed primarily of rock crystal and white quartz, the latter taking its color from very small inclusions of fluid or gas while it formed. This 100% natural clear quartz has been heat-treated to add a special metallicized aura effect.
