hope you are fine and can help us a bit. We have irradiated
quartz from Cristalina-GO-Brazil, making smoky from clear quartz.
Now we are looking to turning them to prasiolite. We have tried
to heat them and would appreciate to obtain any info you think is
useful. We are running a lapidary and silversmith school working
with disabled students.
