I am wondering, what kind of diamond grading do they do in Europe? Specifically Switzerland? We are flying out to a jeweler there soon and realized though I'm educating myself on this forum, most of the grading here are GIA... Do they also have GIA in Europe?
You will rarely find GIA or even less AGS graded stones here in Europe.
The better stones are mostly graded by HRD in Antwerp. You will find a lot of ungraded stones and some IGI and EGL and every European country has its own grading lab.
