The Bureau of Indian Standards (BIS) has for the first time established the Indian standards on the quality parameters and grading of the polished diamonds in the country.
The BIS, the National Standards Body, after putting in five years of research, has established Indian Standards on grading of polished diamonds in line with the International norms, so that the diamonds certified against these standards are accepted globally.
Currently, the Indian Standard(IS) for diamond is IS-15766, which is include in two parts such as classification and test methods.
Grading of diamonds should be considered as per the colour, cut, clarity and carat and other test method criteria established by the BIS.
There were no formal standards adopted by the Indian diamond industry for grading diamonds.
This is the first time in the country, the BIS has established Indian standards for diamonds.
