Quartz (SiO2) can come in a range of shades and opacity but is most widely recognized as white or colourless. The colour of sand deposits depend largely on the variety of minerals and country rock detritus that make up the resource. The Shaw Resources Natural Silica Sand deposit (>98% SiO2) contains abundant rock crystal and citrine quartz, with lesser milky quartz, smoky quartz, amethyst, and rose quartz. This combination gives the sand a pure white to buff hue and makes it excellent for filtration sands, blasting abrasives, and a variety of decorative uses!
