In Naples, there is a small village known as the goldsmiths’ district, which has hosted the workshops of Neapolitan master goldsmiths since the time of the Angevins; their creativity, skill, and passion have created the foundations for the Great Neapolitan School of Jewelry, famous all over the world.
Color is a fundamental element in the evaluation of a diamond. The greater the intensity of the white, the higher the value of the diamond. Nardelli guarantees, through analysis conducted by its specialized personnel, the color grading, specifying it on the warranty validation tag.
Diamonds are classified based on a scale known as “master stones,” established by the Gemological Institute of America (GIA), which ranges from colorless shades (D) to shades with increasingly pronounced yellow hues (Z).
Carat represents the unit of weight for diamonds.
One carat is equal to 200 milligrams. One carat can also be divided into 100 “points” or hundredths of a carat.
The size of the diamond increases its value and rarity. However, they are of lesser importance if not associated with a good degree of color and clarity, as well as a properly proportioned cut.
Size significantly contributes to increasing the value of a diamond, as larger stones are rarer than smaller ones. A 5-carat stone is valued more than five 1-carat stones of equal quality. Nardelli diamonds, considering the set of these evaluation parameters, are among the best available on the market today.
The diamond frequently exhibits interruptions within its crystal lattice due to a series of phenomena defined as “inclusions,” which can take the form of small crystals, clouds, feathers, flaking, carbon spots, etc.
Inclusions are true fingerprints of the diamond, attributed by nature, making each stone a unique piece. The fewer these imperfections are present, the closer the diamond, through a grading system, approaches purity.
Inclusions are evaluated on a scale of perfection established by the Gemological Institute of America (GIA).
The purity scale ranges from I.F. (flawless = free of imperfections) to P.I. (included = included), based on the visibility of inclusions under 10x magnification.
The degree of purity of a diamond is determined by the number, position, and size of the inclusions present in it. Nardelli diamonds are examined and meticulously checked by highly qualified personnel to ensure that each individual stone reflects the highest degree of purity.
