The quality of a diamond is evaluated using four fundamental parameters: Cut, Carat, Colour, and Clarity However, Mirco Visconti adds a further and personal parameter: Choice or rather the “Fifth C,” undoubtedly the most important parameter to guarantee the perfect diamond for every jewel.

Compliancy with each parameter is classified and validated in Mirco Visconti’s laboratory by H.R.D. (Hoge Raad Voor Diamant) of Antwerp and IGI (Italian Gemmological Institute) certified expert gemmologists with the use of the best technologies available.
  • CUT
The weight of a diamond is measured in carats, which correspond to 1/5 of a gram. In its collections, Mirco Visconti offers jewels with diamonds of different carats and therefore, of varied sizes, in order to fulfil any wish.
In diamonds, colour is a brightness parameter that indicates the colour saturation scale. The degree of colouring is classified with letters starting from D (perfectly colourless diamond) up to Z (diamond with intense colouring). For its jewels, Mirco Visconti exclusively chooses colours between grade D and H, the best quality that can be selected today.
Cutting is the art of giving shape, charm, and beauty to a diamond. From the typically classic 57 facets round brilliant cut to the most refined pear shape or emerald cuts, for its diamonds Mirco Visconti chooses the most refined cuts, in order to enhance the characteristics of each individual stone. The ideal cuts for shape and symmetry allow for the light to be entirely reflected in the diamond, emphasising its brightness and brilliance.
In the lengthy process of consolidating its crystalline structure, traces of small imperfections may remain inside the diamond. The degree of purity indicates the presence or absence of inclusions visible under 10x magnification Mirco Visconti usually selects diamonds with a degree of purity varying from IF to SI.

The perfect cut is the cut that enables the diamond to completely reflect the light. On the other hand, an imperfect cut prevents the complete reflection of light, and the diamond loses brilliance.

Choice is the value that Mirco Visconti adds to his creations because only an expert eye can recognize the “perfect” diamond. The secret is in the brilliance and only a very small proportion of the stones passes the strict selection. That's why the stones selected have a value that goes beyond market, regardless of their size.


The diamonds used by Mirco Visconti do not come from conflict zones or arms trafficking and do not exploit the dignity of those who extract them but, on the contrary, they provide a source of lawful and fairly paid employment. This is guaranteed by exclusively purchasing from suppliers adhering to the Kymberly Process Certification Schemes (KPCS). It is an international agreement between the UN and governments of countries, the diamond industry, and non-governmental organizations.

Each lot of diamonds is accompanied by a certificate attesting that diamonds come from sites with no relation to armed conflicts. Diamonds can only be exported to a KPCS member country and whenever they change ownership, they must be accompanied by a Guarantee. Like the one that accompanies each Mirco Visconti sales document.

MIRCO VISCONTI S.P.A. all our diamonds are purchased from suppliers who apply the World Diamond Council System of Warranties based on the Kimberley Process in order to ensure they have been purchased from legitimate sources not involved in funding conflict and in compliance with the United Nations resolution.
