The US and Canadian Mines:
In the past few years less gem rough is being mined in the
US and Canada. By buying rough in the US and Canada, American
and Canadian gem cutters could count on humane mining practices,
local availability and surety about natural (untreated) material
before doing a lab report.
You can read more about some of the Canadian mines at

International trade in rough and cut gemstones is just as
complex as war, poverty and politics — and profoundly
impacted by them all. For a quick tour of current conditions,
