Dear Joshua,
Geological conformity is the relationship between adjacent conformable geologic strata, which is irrelevant to our discussion. Perhaps you are referring to uniformity rather than conformity? If so, trigonal quartz surface features can be both uniform and regular. See photo example:
Twice you use the oft-misapplied term “clear”. When referring to mineral clarity, the correct term is “transparent”. When referring to body color, the correct term is “colorless”. You wrote “it would be far less likely to find a clear piece of “natural glass" in similar size than it would diamond”. I am of the exact opposite opinion.
Your year of research and study was totally unnecessary. A thirty second (yes, 1/2 minute) RAMAN-532nm test would tell you 100% conclusively wether it is diamond or not. Put your money where your mouth is and send a sample to GIA, AGL or Stone Group Laboratories for a conclusive report. Or, I would be happy to do it for free in my lab in Bangkok and publish the results with screenshots of the RAMAN spectrum.
Finest regards,
