There is an embargo on Burmese goods for a very good reason- purchasing Burmese stones helps support a repressive, totalitarian, even genocidal government.
I think you may have this wrong. I believe the gems are smuggled out
of Burma to AVOID supporting the Burmese government. If buying the
smuggled gems helps anyone it is the Karen opposition and the miners
and smugglers themselves. If anyone is supporting the government it
would be those who buy gems legally at the government auctions in
Rangoon (Yangon, as the current government would have it).
