The corundum crystals embedded in the matrix are mixed crystals that, depending on the iron, chromium or titanium content, appear in colors from dark blue to violet to red (sapphire --> ruby). This is why even dark blue sapphires still fluoresce bright red under UV light, which pure sapphires from other locations do not.
