Highly unlikely, the melting point of those materials is higher than most house fires. The boiling point would be even higher. Even then, the amount of beryllium in all of those gems combined wouldnt be enough to significantly impact the air quality.
I didn’t want to get into a discussion of vapor pressures, so I was just using those temperatures as stand-ins to get an idea of what temps would required. But you’re right, I probably should have used the sublimation temp.
