This sand is from the Big Sur coast of California, with many metamorphic rocks created near an ancient subduction zone. The sand on the right is 100% composed on shells, coral skeleton, and other biological precipitates.
Not all Quartzite is pure quartz. For instance, a muddy sand like along some of the Gulf of Mexico coast, or a lime sand like most Caribbean beach sand, when changed into Quartzite, has a lot of non-quartz material in it that can make the resulting stone more brittle, subject to denting and etching and staining, etc.
