I need help identifying this rock. It was found as shown in a delivery of limestone gravel used to form the base of a concrete paver sidewalk. The project was located on Neville Island, PA but the limestone gravel was delivered from a landscape supply yard. I have no idea where they purchased their limestone.
Thanks for your help. I am just curious and want to maybe make a paperweight/pencil holder for my desk. It is quite heavy and non-magnetic.
