Ruby is essentially just the compound aluminum oxide (Al2O3) doped with chromium (which makes it red). The Cr3+ ions occupy only a very small percentage of the Al3+ positions in the crystal lattice, so the molar mass of ruby is essentially the same as aluminum oxide: 2 (26.98) + 3 (16.00) = 101.96 grams / mole
