Quartzite is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals.

You will get a set of ten Quartzite rocks approximately 1 inch in size.

Great for classroom rock collections, science fair projects, and geology demonstrations.

Please be aware that this is a natural mineral, and as such, each piece is one of a kind! The set you receive may not be the same as the ones pictured, but it will be similar. Rocks come in irregular shapes, sizes and weights.
