Selection of diamonds
Gival selects its diamonds with the international criterion determined by the 4 fundamental characteristics of diamonds, recognized by all gemological institutes in the world.
Selection of precious stones
The Gival brand carefully selects all the precious stones of its collections, using exclusively "natural precious stones" that are purchased with an ethical supply chain directly from the source: sapphires, rubies, emeralds, aquamarines, morganites, tanzanites, tourmalines, etc. are chosen for cut and color, to be worthy of being.
Each Gival jewel is accompanied by a personalized gemological certificate with its photo, which certifies and guarantees, in a transparent and objective way, the high quality standard: both for the selection of diamonds and precious stones, both for the careful processing of gold, for the microscope setting, and for the exclusive realization in our laboratories in Italy.
