White diamonds are a classic. Colored ones are in fashion. But gray diamonds are in trend. There is only one problem: gray diamonds are rare, very rare. But they are considered very chic, also because they are perfect to combine with other colors: gray is a shade that manages to coexist with all the others, as well as alone. A gray diamond, in fact, is suitable to be combined with any dress and can be worn at any time of day.<\/p>\n Features.<\/strong> Gray diamonds are extracted in India, Russia, South Africa and Australia. The gray color comes from a high concentration of hydrogen or boron. But not only: gray diamonds often have different shades, due to a slight influence by other mineral elements.<\/p>\n Colors.<\/strong> According to the Gia (Gemological Institute of America), there are many types of gray diamonds, even with extra coloring. There are Gray Purple, Gray-Blue, Gray-Green and so on. In addition, gray diamonds are also cataloged for color intensity: Light Gray, Fancy Light Gray, Fancy Gray, Fancy Dark Gray and Fancy Deep Gray. The most common shades according to Gia are yellow, green, blue and purple. The human eye, on the other hand, can distinguish about 500 shades of gray.<\/p>\n The cost.<\/strong> The price of diamonds is determined by color, but also by clarity and, of course, by size. The famous four Cs that are used to classify diamonds, which indicate the initials of the four terms in English, namely: color, clarity, cut and carat, also apply to gray diamonds. In general, gray diamonds cost a little less than brightly colored ones, such as yellow or pink. And they also cost less, on average, than colorless ones.<\/p>\n![\"Collana](\"https:\/\/gioiellis.com\/wp-content\/uploads\/2017\/05\/collana-monique-pean-1.jpg\" "\\"\\"")
