QUARTZITE

Quartzite is microcrystalline quartz, formed from sandstone subjected to the heat & pressure of tectonic compression.  Usually white or grey in colour, translucent when cut into thin sections, it is perhaps not the most interesting gem material in its own right, but it often forms the matrix in which more exotic & attractive minerals are held.
