Guys,
Kindly advise if there is any offcial rough stones categorization - e.g. one from DTC for gems
For example which say that for formation of price they use the crystalline shape, the rough weight, the color and the clarity and which specific subcategories for each
Would be happy to get any kind of categorizations with sources or just kindly inform if there are no such a things
Cheers,
Andrii
