AL2O3:CR is the chemical make up of a ruby, that means that every molecule in it has 2 atoms of aluminum, 3 atoms of oxygen connected to an atom of chromium. The atomic weight of AL is 26.98, O is 15.99, and CR is 51.99. If we add them up in their proportions we get a weight of 153.92 for each atom of ruby. According to the Periodic Table Gold has a weight of 196.97, there is no way that a ruby of equal size will be heavier than gold.
