If 1000 people with geeky interests all try to make this stuff I would be surprised if one did not get lucky with the variations in their uncontrolled home lab environment and hit the perfect sequence for making a grain of it... unless the material does not exist; but honestly if you want to hear the opinion of some person on the internet, I think that it is real.

That may be true, but I'm not seeing 999 other people with geeky interests reporting their failed attempts. We are, however, starting to see actual labs reporting negative results.
