  1. Natural green diamonds guide: prices, authenticity, history & more.

  2. Green diamonds are among the most wondrous works of nature, created in a unique process spanning over millions of years. They include some famous breathtaking diamonds in unique vivid shades. The special story of green diamonds places them somewhere in the middle of the spectrum between the rarest of diamonds and those more commonly priced despite being very rare. How do they form? How much do they cost? How rare are they? All that and more, in this article.

  3. How are natural green diamonds formed? The green color in natural green diamonds originates from radiation the diamond crystal is exposed to during and after its formation. This formation process, be it of a colorless or fancy colored diamond, takes place under conditions of high pressure at a depth of 150-200 kilometers below the ground, at temperatures ranging from 1,000 to 2,000 degrees centigrade over millions of years. While colored diamonds usually form as a result of a "contamination" in the pure carbon crystal (such as yellow diamonds, created by the presence of nitrogen molecules), the green color generally occurs after the diamond has completely crystalized, usually when it makes its way out from the deep underground through volcano vents and is thereby exposed to direct radiation.

  4. The intensity of a diamond’s green color is significantly influenced by the type and duration of radiation it is exposed to, as well as its size. Alpha particle radiation penetrates the diamond, affecting only its skin tone. Since this radiation does not penetrate into the body of the diamond, it acquires a rare and valuable, light green color. In contrast, beta and gamma radiation are particulate radiations that can penetrate the diamond’s body and give it a deep green color at higher intensities, such as Fancy Intense, Fancy Deep & Fancy Vivid. Green diamonds that come in contact with natural beta and gamma radiation are so rare, mainly because these conditions occur in nature in only 0.1% of cases.

  5. Fancy green diamond: color & pricing

  6. The green diamond price, like all fancy colored diamonds, is influenced primarily by its color. The color of a Fancy diamond is the key parameter determining its rarity and pricing, and it leads the rest of the parameters by far. The color scale of the world's leading gemological institute, the GIA, is divided into 9 color intensities: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep, and Fancy Dark. Faint representing a bright and pastel shade and Fancy Deep representing a strong and deep green color.

  9. Since the diamond’s green color is created by direct exposure to radiation, only the areas that are subject to such exposure will acquire a green hue. Subsequently, most green diamonds exposed to a superficial alpha radiation that doesn’t penetrate the diamond’s casing have an uneven color distribution, making green diamonds with equal distribution particularly rare. Compared to Skin Tones diamonds, green diamonds exposed to beta and gamma radiation that penetrates the diamond’s body usually get not only a spectacular and extremely rare color intensity, but also a more even and uniform color distribution that enriches the diamond’s appearance, enhances the color, and gives it a much higher monetary value.
