Green diamond: a rare color, a fascinating story

Why is the green diamond so fascinating?

The green diamond is one of the rarest and most intriguing gemstones in the world. Unlike other colored diamonds, its natural green hue does not come from chemical impurities but from exposure to natural radiation over millions of years. This slow, exceptional geological process gives the green diamond its singular, subtle color.

A unique formation deep within the Earth

Green diamonds form like all diamonds: under high pressure and temperature, several hundred kilometers below the Earth's surface. What sets them apart is that they are later exposed to natural radiation that slightly alters their atomic structure. This produces a green coloration, sometimes on the surface, sometimes deeper within the stone. Although caused by natural radiation, this phenomenon is completely harmless to human health and poses no risk when the jewelry is worn.

This natural alteration is extremely rare: it is estimated that fewer than 0.1% of mined diamonds show a green hue of natural origin. This extreme rarity, combined with how difficult it is to certify the origin of the color, explains the exceptional value of these stones.

Shades of green: a rarity in itself

Green diamonds come in a range of hues from pale green to intense green, sometimes with bluish or grayish overtones. The color may be even or varied, and the more vivid the hue, the rarer and more precious the stone. It is a palette that increasingly appeals for a diamond engagement ring unlike any other.

Some green diamonds are artificially treated, but those whose color is 100% natural (certified by laboratories such as the GIA) are highly prized.

The green diamond in history: a few iconic examples

Among the few known green diamonds, three stand out for their exceptional history and rarity:

The Dresden Green Diamond:

Probably the most famous of all, this 41-carat diamond is on display in the Green Vault in Dresden, Germany. Its intense, perfectly even green color makes it a worldwide benchmark. Discovered in India in the 18th century, it is said to have belonged to Augustus III of Poland, who reportedly acquired it to adorn his royal crown. The jewel has survived eras and regimes, and was carefully protected during the Second World War.

The Aurora Green Diamond:

This 5.03-carat intense green diamond is considered one of the most valuable ever sold at auction. It was offered by Christie's in Hong Kong in 2016 and sold for more than $16.8 million, setting a world record for a green diamond. Mounted on a ring signed by Moussaieff, the jewel stands out for its vivid color, exceptional clarity and GIA certification of natural color.

The Ocean Dream Diamond:

This exceptional 5.5-carat diamond is famous for its unique hue between green and blue, an extremely rare shade. It is said to have been discovered in Central Africa and is one of the few diamonds to combine an intense aquatic color with natural color certification. Put up for auction by Christie's in 2014, it reached a record price, cementing its status as an iconic piece.

These rare stones are admired not only for their beauty but also for the stories they carry across centuries and continents.

How a green diamond is assessed

The value of a green diamond is assessed on several criteria:

Hue: the more vivid and even it is, the rarer the stone
Clarity: as with all diamonds, inclusions affect the value
Carat weight: stones above 1 carat are very rare
Cut: a cut that enhances the color increases the value
Natural origin: certified by an independent laboratory

How much is a green diamond worth?

Natural green diamonds are among the most expensive on the market. A certified stone, even a small one, can reach considerable sums. In 2014, the 5.5-carat "Ocean Dream Diamond" sold at Christie's for more than $8.6 million, a record for a diamond of this color. In 2022, a documented private sale of a 3.1-carat natural green diamond certified by the GIA reached more than €3.2 million, confirming strong demand in this segment. The price varies with the criteria mentioned above, but also with origin: certain mines in Africa or Brazil are known for having produced unique specimens.
