All Gival jewels are born from a careful research of continuous fashion trends and from a deep and passionate work of our expert craftsmen, masters in enhancing the light and colors of precious stones and diamonds, transforming them into eternal jewels, capable of transmitting emotions, passions and traditions. From the idea comes a drawing made by hand and designed in the smallest details, to then be made with the traditional system by expert goldsmith craftsmen through 10 fundamental phases: design, prototype realization, gumming, casting, finishing, selection of diamonds and precious stones, setting, cleaning, rhodium plating and quality control.


Gival selects its diamonds with the international criterion determined by the 4 fundamental characteristics of diamonds, recognized by all the gemological institutes in the world. The four characteristics of diamonds are:

Carat: the carat is the weight unit used for diamonds. One carat corresponds to 0.2 grams or one a fifth of a gram. To make it easier, a carat is divided into 100 points.

Colour: the color of diamonds ranges from white to smoky yellow. The whiter the diamond is, the more precious it is. Classification of the colour is based on a scale called “master stones” under standardized artificial light conditions, equivalent to daylight in the northern regions. The range of colours is required only to differentiate between the shade. Colours are defined using alphabet letters from D to Z. The best colours are D, E, F and G, that are used by Gival.

Clarity: a diamond is considered pure if it does not have any inclusion, and to determine the presence or absence of inclusions, it must undergo examination, magnified 10 times and in normal light conditions, by a qualified person. A whitish inclusion is preferable to a black one of the same dimensions. Other criteria which determine the grade of purity are the dimensions, position, number of inclusions and brilliance. The highest level of purity is identified with the code IF- VVS.

Cut: the term “cut” means the exact shape of a diamond. An imperfect cut means it is impossible to have a perfect brilliance. The weight of diamonds is often sacrificed to have a perfect cut. A perfect cut is defined as: VG VG (very good – very good).


Gival 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 by cutting and color, to be worthy of being set in a Gival jewel.


Each Gival jewel is accompanied by a personalized Gemological Certificate with relative photo, which certifies and guarantees, in a transparent and objective way, the high-quality standard: both for the selection of diamonds and precious stones, and for the accurate goldsmith workmanship, for the setting under the microscope, and for exclusively realization in Italy in our laboratories. It also certifies that the entire production chain is carried out according to an ethical process.


Gival carefully selects its diamond suppliers, ensuring that they come exclusively from countries that adhere to the Kimberley Process global self-regulation program. The Kimberley Process Certification Scheme (KPCS) is the most prominent international standard for diamonds. This is a government-controlled and government-led certification agreement, launched in 2003, aimed at ensuring that profits from the diamond trade do not go to finance civil wars. The trade in diamonds is allowed only from places where the extraction work is controlled, protected and ethical, making diamonds “pure” like the soul of Gival jewels.
