This is a very large piece of natural coral. There is a slight blue tinge to the coral, though it appears more gray in photos. The specimen does not stand on its own: buyer will need to find a way to support it or mount it. There are a few areas where the coral has broken. There are also some red colorations on parts of the coral (please see photos). Overall, this is a very large, very beautiful specimen that allows you to bring a piece of the ocean into your home.
