A diamond’s clarity has a direct effect on the beauty of the stone and on its price. The clarity of a diamond not only depends on the number of natural imperfections in a diamond (known as inclusions), but also on the size of these inclusions and their position in the diamond. All diamonds can receive a clarity rating based on an industry standard scale. The highest position of the ranking is “IF.” A diamond is said to be “Internally Flawless” if, even under a 10 x magnifying glass, no internal flaws and no external imperfections are visible. A Flawless diamond is extremely rare and priced accordingly. At the bottom of the ranking is “I3,” which means that imperfect inclusions are visible to the naked eye.
ISTANBOULLI GIOIELLI diamonds are selected only between IF and SI1, which guarantees a high level of clarity with only very small inclusions, which are not visible to the naked eye.
