Limestone and others


Quartzite is very hard, metamorphic rock which was originally sandstone. Through heating and pressure usually related to tectonic compression within orogenic belts, the original quartz sand grains and quartz silica cement were fused into one. Pure quartzite is usually white to grey. Quartzites often occur in various shades of pink and red due to varying amounts of iron oxide. Other colors are due to impurities of minor amounts of other minerals.

Because of its hardness (about 7 on Mohs' scale of mineral hardness), quartzite is harder than most granites which make them very conducive for countertops or decorative stones. Many designers and architectural firms are specifying quartzite in bars, high end restaurants and commercial buildings due to their hardness, resilience and translucent properties.
