G for Green DiamondAnna S.
Among all the fancy colored Diamonds, natural Green Diamonds are one of the rarest and the most sought-after gems. They are an epitome of exclusivity.
Green Diamonds get their sophisticated stunning color from radiation exposure or from complex defects including nitrogen, hydrogen and nickel impurities:
- Diamonds colored by radiations typically have pure green or blue-green shades
- Nitrogen defect leads to a combined yellow-green appearance of a Diamond
- Green Diamonds colored by hydrogen commonly have brown or gray shades
- Nickel defects produce an overall yellow-green color
Currently, most of the world’s production of fine natural Green Diamonds comes from South America or Africa.
The largest Green Diamond is the famous 40,7 ct pear-shaped Dresden Green that was found in Golconda mines in India sometime before its earliest historical record in 1722. Frederick Augustus II – the elector of Saxony, king of Poland, and grand duke of Lithuania – bought the diamond in 1741 at the Leipzig fair from a Dutch merchant by the name of Delles.
Several other world renowned Green Diamonds were sold in recent years. Among them are the 5,51ct blue-green Ocean Dream, the 25ct Gruosi Green, and the 5,03ct Aurora Green sold at auction in 2016 for more than US $3.3 million per carat.
Green diamonds are considered very rare – however they are inferior in this, for example, to blue diamonds. These gemstones are suitable for investment, if they weigh more than a carat and have a Straight or Intense overtone.
