We are currently on the hunt for our countertops. My original plan was to go with a calcatta quartz. I was at a stone yard yesterday and the sales person brought me to see some quartzite. I found one slab i love but when I got back home and did some research it seems this slab may be truly calcite and not quartzite. My first question is it possible to tell from the pictures below? second, i’ve read some not good reviews on calcite as it is as soft as marble. Wondering if anyone has used it in a kitchen with success keeping up with regular maintenance?
