Colours in gemstones - a category that I'm pretty sure includes ilum crystals - are simply chemical impurities that got into the stone. The ruby, for instance, is only red because some chromium got in there. Since the construction of artificial diamonds and other precious stones is commonplace even today (industrial diamonds are admittedly not gem-quality, but w/e.), it is not that big of an ask for the boffins at DoSAT to synthesise an ilum crystal containing the particular chemical impurities to render the beam blello.

Why you'd want to, of course, is a different matter. =]
