TEll me more about using calcite

Known for its sparkly nature, 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 appearance, they can sometimes be mistaken as quartzite. 

Although they look like quartzite, they are very different in terms of durability. Calcite is closest in durability to marble, it can scratch, etch, and stain - however is slightly more forgiving than traditional marble. Common substances used in the kitchen, like tomato sauce, lemon juice, and wine, are acidic and can etch your countertop if they are not wiped up. Staining can be avoided by sealing your stone (but the sealer will not prevent etching). Make sure you fully understand the pros and cons of calcite before selecting one. 

Like with marble, a honed or leather finish is often used to help disguise any imperfections that are caused over time.
