So here's a thought: could you take a corundum crystal and dope one portion with Fe Ti to get a sapphire blue, and the other part with vanadium to get an amethyst hue. It wouldn't be exactly the all, but it would give the look of it. I have no doubt it would be prohibitively expensive to figure out the process, but... Is that even theoretically possible?
