Dry Rock? Live Rock Decoration Layout Coral Aquarium Saltwater Fish Rocks Stone

Purchased from a tropical fish shop.
As I am an amateur, I cannot determine if it is artificial or natural, nor the material.
It was used for about half a year in a 60cm aquarium (with about 6 fish). There were no problems with the fish.
I am listing this item due to a change in my aquarium layout.
