Thanks for the perspective. I'm guessing these are super high pressure kilns. People learn that we have a "sapphire screen" and don't seem to remember that only about ten years ago an these artificial gems being massed produced seemed like a pipe dream. I figure however, that there is going to one day be a laser/gas (with interferometry) process that allows creation of a high pressure crystal on a surface, one molecular layer at a time.
