Home of the GIA, which sets the global diamond standard, where the Graduate Gemologist diploma you earn is recognized at every bench on earth.
People were hammering gold into ornaments long before anyone wrote. Near Varna, on Bulgaria’s Black Sea coast, a cemetery dated to about 4500 BC held some three thousand gold objects, the oldest gold jewellery yet found. Renaissance Florence made the goldsmith’s bench a school for artists: Filippo Brunelleschi was apprenticed as a goldsmith at fifteen and became a master in 1398. In 1593 Grand Duke Ferdinando I cleared the butchers and fishmongers off the Ponte Vecchio and forbade any trade on it but precious metals. Florence is where that bench is still most visibly alive: the bridge is home only to small jewellers, and through some workshop windows you can still watch goldsmiths making pieces by hand.
Learn to grade a diamond where the global standard is set, for a diploma every bench on earth knows.
The body that sets the global diamond standard is here, and the diploma it awards is read at every bench on earth — so the company is people earning the same credential rather than a trade quarter you walk into. Nothing outside the institute describes a scene, and nobody of ours has been.

There is a real difference between a school that teaches you and a good-looking website, and too much of the internet is the second kind. Four instruments do the work, and every one of them is visible on the page you are already on.
If a place dodges these, that's your answer. It costs you nothing to ask, and it tells you everything.
This is the short version. The full method is here — the six questions, in order, for any craft anywhere.
