I'm curious about the origins of mystic gems like quartz & topaz. Are these stones found in the ground that way, or are they treated?

I don't mean muderers or terrorists, or anything like that. I mean, we are in a time where tectonic movement is speeding up (extremely slowly, though), faults have greater tension building because they cannot release minor quakes, the Earth's magnetic field is due to reverse, we are due for a new iceage, more violent volcanic activity more often, greenhouse gasses being realesed not by just human activity, but by all living things (not helped by shortage of plants to provide oxygen and get rid of CO2).
And on top of all that, the Yellowstone Supervolcanoe [which erupted last almost exactly 7000 (or 70,000- I don't remember exact)] erupts every 7000 (or 70,000-I'm not sure which) years.
I'm not asking if humanity can survive it if it all happened at once- I'm asking how bad is the danger and will any life at all survive it the world unleashes it all at once.
I'm not saying that it will happen all at once-it probably will be spread out over the next 1500/3000 years. What will happen?
