Crushed Clear Quartz (Rock Crystal) from Brazil, Medium Crush, Sand Size, 2mm - 0.25mm

Quartz is the second most abundant mineral in the Earth's crust. Many gemstones, such as amethyst, rose quartz, and citrine, are quartz varieties that have trace amounts of other elements within their crystalline structure. These trace elements produce the variety of colors that we see in quartz. Just like other minerals, quartz can have inclusions and can vary in clarity. This particular quartz is from Brazil and has great clarity with little to no inclusions. This type of quartz is also known as "rock crystal".

Our medium material is considered to be sand sized (very coarse sand to fine sand), ranging between 2 millimeters to 0.25 millimeters. Please see the corresponding sediment size chart.
