The first sorting is made at the time of out come from the mine or at the time of purchase. Results are mostly double checked by independent gemology expert. In case we export rough diamond to our cutting and polishing facility in Antwerp the second sorting and evaluation is made there. If the stones have to be delivered to our clients, the next sorting and evaluation is made at the country of origin and the buyers should come with their gemology expert. After the price settlement is done, the stones are certified by the KP Officers of the country of origin for further export and our management arranges the export formalities. For sorting and evaluation we use usual gemological equipments.
