If its very heavy then its not onyx, which is relatively light. Can you scratch it on the back of an unglazed porcelain such as a tile to determine its streak? If the streak is red, then its almost certainly hematite. If the streak color is black, white, gray, or brown then further ID will need to be conducted.
