Fancy Green Diamonds: A Rare and Exquisite Gemstone

Diamonds are often associated with colorless stones that sparkle with brilliant fire, but they come in a range of hues, including fancy green diamonds. These rare and exquisite gemstones are highly sought after for their unique beauty, with prices that can rival those of colorless diamonds of the same carat weight. In this article, we will explore the origin of the color, color spectrum, and range of fancy green diamonds, how they are valued, and the mines where they are found.

The color in fancy green diamonds is caused by the presence of natural radiation in the earth’s crust during the diamond’s formation. The radiation alters the crystal structure of the diamond, resulting in a green color. The exact cause of the radiation is still not fully understood, but it is believed to be the result of the decay of naturally occurring radioactive elements such as uranium and thorium.Fancy green diamonds come in a range of hues, from light yellow-green to deep forest green. The intensity of the color determines the value of the diamond, with the most vivid and intense greens being the most valuable. Some fancy green diamonds have secondary colors, such as blue or yellow, which can add to their uniqueness and value.

Fancy green diamonds are found in several mines around the world, including Brazil, Zimbabwe, and Venezuela. The most famous mine for fancy green diamonds is the Golconda mine in India, which was the primary source of these diamonds in the past. However, the mine is no longer active, and most fancy green diamonds on the market today come from other sources. Diamonds are formed deep within the earth’s mantle, where extreme heat and pressure transform carbon into crystalline structures. Fancy green diamonds are created in the same way as colorless diamonds, but their green color is the result of natural radiation during the diamond’s formation. The chemical structure of a fancy green diamond is identical to that of a colorless diamond, with carbon atoms arranged in a cubic crystal lattice.

The value of a fancy green diamond is determined by its color, carat weight, clarity, and cut. The Gemological Institute of America (GIA), a non-profit organization dedicated to research and education in the field of gemology, grades fancy green diamonds based on the intensity of their color. The grades range from Faint to Fancy Deep, with Fancy Vivid being the most valuable. Fancy green diamonds have a long and fascinating history. They were highly valued by royalty and the wealthy in ancient times, and were often used as adornments in crowns and other jewelry. The famous Dresden Green diamond, a 41-carat green diamond, was once owned by the kings of Saxony and is now on display at the Dresden Green Vault in Germany. In recent years, several high-profile green diamonds have come to market, including the 5.03-carat “Aurora Green” diamond, which sold for $16.8 million at a Christie’s auction in 2016

In conclusion, fancy green diamonds are a rare and exquisite gemstone that are highly valued for their unique beauty. They are formed by natural radiation during the diamond’s formation, and come in a range of hues from light yellow-green to deep forest green. The most valuable fancy green diamonds have intense and vivid colors, and are graded by the GIA based on their color intensity. These diamonds are found in mines around the world, and their chemical structure is identical to that of colorless diamonds. Fancy green diamonds have a rich history, and continue to captivate collectors and enthusiasts with their exceptional beauty and rarity.
