It is still a common belief that every polished stone is marble.
In fact, the difference between marble and granite is very big.
Marble is a carbonate rock that is easy to grind and polish but has lower hardness compared with granite. The products made of this material are not resistant to the adverse weather conditions, which makes them suitable mainly for enclosed spaces.
However, marble is much more richly colored and patterned than granite.
The products made of granite materials are practically eternal.
