Here's a possible way for a DIY materials science enthusiast to try synthesizing it cheaply: synthesize graphene using a blu-ray player[0], spray with liquid glass[1], then reduce to get rid of the O2 in SiO2. I'd try it, but I have too many other projects going on... if anyone tries it, let us know if it works out.
Edit: thinking about it more, it would be kind of hard for a DIY enthusiast to reduce with e.g. the household kitchen oven. Still, a university lab could try it rather easily.

- mchannon 15y agoReducing SiO2 to Si requires extremely high temperatures (2000°) and sucks up all nearby carbon (bye bye graphene). Even most university labs will have trouble coming up with the temperatures required, particularly considering you want to keep the oxygen from air out (and the carbon monoxide product away from air-breathers).
