Please help me identify this unique looking rock.

Hello Admins and all members. I need your help in identifying this rock I recently found. I live in southern NJ, its about 30 lbs, and its been cleaned. When doing a google image search the two possibilities were Antlerite and Cuprite. But those characteristics dont match the pics of my rock. Thank you all in advance for your assistance in trying to help me figure this out. I have been collecting rocks and fossils since a young child but have never seen a rock quite like this one before. I dont know what it is.

Juicyfroot76 What is the blacklight test consist of and how is it performed/what am i looking for? Also how does one go about conducting a hardness test and what tools do I need? Results wise I dont know what they tell you after youve done the tests. Any help would be much appreciated and yes I do agree that I need to do these tests. Thanks for your comments.
