Calcites are typically white and translucent and can have soft veins of light blue, gray, green and other light colors. Because of their grain structure and quartz like appearance, they can sometimes be mistaken as quartzite. Although they look like quartzite, they are very different in terms of durability. Calcite is soft and can scratch, etch and stain just like marble can. Make sure you fully understand the pros and cons of calcite before selecting one as a kitchen countertop. Calcites are better suited for a bathroom environment.
