Although priced much cheaper, uncured rock will basically mean you will need to commit extra hours cleaning the rock of decomposed materials and bearing with the stench before you can place into your aquarium.

There are also special request types of live rock harvested from different location in deep sea but be prepared to pay heavy price to acquire it.
