Products from GIA
The Gemological Institute of America (GIA) was founded in 1931
Decades before the introduction of grading centers in Europe, there was already a corresponding institution in the USA: The "Gemological Institute of America" (GIA) has existed since 1931 and since then has contributed significantly to the fact that today there are standards for the grading of diamonds. The development of the international classification system for diamonds also goes back to the GIA. However, the graduation levels of the GIA today differ minimally from those of the International Diamond Council (IDC), so the proportions are graduated differently. In our offer overview we have "translated" the graduations of the GIA into those of the IDC for comparability. All information about the diamonds for sale is therefore IDC-compliant, even if only a GIA certificate is available.
