Fancy Color Diamonds

...are considered to be in the premium segment.
Only one in 10,000 diamonds possesses this rare, intense coloration. They offer impressive potential for value appreciation, protection against inflation, and their collector's value sometimes increases disproportionately.

HISTORY

For centuries, colored diamonds have delighted kings, collectors, and enthusiasts—their historical heritage is as fascinating as their rarity.
The closure of the Argyle mine in 2020, the main source of valuable pink, blue, and red diamonds, has further drastically reduced supply and increased the exclusivity of these diamonds.
Fancy color diamonds are not only impressive due to their proven stability in value over decades, but also because they are independent of traditional financial markets.

VALUE DEVELOPMENT

Particularly rare and high-quality diamonds are in demand and show stability in value. The long-term developments are remarkable: since 2005, the Fancy Color Research Foundation (FCRF) has recorded the following increases in value:

Total market: +209.3%
Pink diamonds: +398%
Blue diamonds: +245.4%
Yellow diamonds: +53.6%
In the current market phase, fancy color diamonds are showing an increase in value of around
5-8% per annum.

Red Diamonds

Formation

The rarest and most valuable diamonds are natural red diamonds. They get their color from an unusual plastic deformation of their crystal lattice. Similar to pink diamonds, the red color is not the result of impurities, but is caused by structural changes in the diamond's crystal lattice.

Overtones

The overtones create diamonds in a wider range of red tones. The overtones range from brown to orange. Unlike all other colored diamonds, red diamonds are classified exclusively in the Fancy Red intensity.

sources

Red diamonds have been found in very small quantities, mainly in Australia, Brazil, and Africa. The Argyle mine in Australia has produced some of the most famous red diamonds.

Prices

An NF Red diamond with high clarity can be expected to fetch a price of at least CHF 900,000 per carat.

Fancy Yellow

formation

Yellow diamonds get their bright color from the inclusion of nitrogen atoms in the crystal lattice. Nitrogen absorbs the violet and blue portions of the light spectrum, causing the diamond to appear a rich yellow. The color intensity varies depending on the amount of nitrogen; stones with a particularly strong color are referred to as “canary yellow.” Color grades such as ‘intense’ or “vivid” in high purity grades are rare and valuable.

overtones

Yellow diamonds can have various overtones in addition to their main color. The most common overtones are green, orange, and brown. Diamonds with a pure, rich yellow color without overtones are particularly sought after, while some overtones result in unique color gradations and individual charisma.

SOURCES
  • South Africa: World-famous mines, including the legendary Kimberley Mine, produce many yellow diamonds.
  • Botswana: Significant production of yellow varieties.
  • Canada: Canadian mines also produce yellow diamonds, but on a smaller scale.
  • Australia: Famous for the Argyle Mine – known for pink diamonds, but also yellow diamonds.
  • Russia: The Siberia region is a classic place of origin, but we do not currently offer Russian diamonds.
PRices

Prices for natural fancy yellow diamonds with high clarity range between CHF 8,000 and CHF 12,000 per carat. Rare stones with a color intensity of “fancy vivid” are offered at CHF 18,000 to CHF 35,000 per carat.

Pink diamonds

Formation

Natural pink diamonds get their color from a unique deformation of their crystal lattice. Unlike other colored diamonds, whose color is often caused by impurities such as nitrogen or irradiation, the pink color is due to an unusual plastic deformation of the crystal lattice that occurs during the formation of the diamond under extreme pressure and high temperatures.

This deformation causes a change in the way light is refracted through the diamond, revealing the pink or rose color. Most pink diamonds were found in the Argyle mine in Australia, which was known for its exceptional colored stones before it closed in 2020.

Overtones

Pink diamonds without overtones are usually more valuable than stones with secondary colors. Exceptions include, for example, a “purple” overtone, which increases the value. The overtones make pink diamonds shine in colors ranging from delicate old rose to rich tones.

sources

The most famous and significant source was the Argyle Mine in Australia, which was renowned for its exceptional production of pink diamonds. This mine supplied up to 90% of the world's pink diamonds.
In addition to Australia, pink diamonds were also found in smaller quantities in other regions, including:

Canada and Brazil.

Due to their rarity, pink diamonds are highly sought after and valuable on the global market, making them one of the most sought-after colored diamonds.

Prices

A high-clarity NF pink diamond can be expected to cost between CHF 100,000 and CHF 150,000 per carat. For a fancy intense/vivid stone, the price rises to between CHF 170,000 and CHF 700,000 per carat.

Fancy Orange

Formation

Fancy orange diamonds owe their bright orange color to the incorporation of nitrogen atoms in the crystal lattice. Unlike yellow stones, the special distribution and concentration of this nitrogen causes a different light absorption, resulting in the characteristic orange hue.
Further structural distortions caused by natural pressure and high temperatures during diamond formation can further enhance the orange color.
Orange also stands for warmth, energy, and creativity and is an eye-catcher in jewelry, which further increases demand.

Overtones

Fancy orange diamonds usually display tones ranging from yellow-orange to orange-brown. Diamonds with a pure orange tone are extremely rare and are almost on a par with rare red fancy diamonds. Overtones such as yellow, brown, or red may occur and influence the individual appearance and value of a stone.

Sources 
  • South Africa: One of the world's leading regions for diamond mining, including orange diamonds.
  • Australia: The Argyle Mine is known for colored diamonds and has also produced orange stones.
  • Canada: Orange diamonds are also found here, but only as rare individual finds.
prices

Prices for natural fancy orange diamonds with high clarity start at CHF 200,000 per carat. Stones with intense or very vivid (“fancy intense”/“vivid”) coloring cost up to CHF 900,000 per carat, placing them in the highest price categories for fancy color diamonds.

Fancy Green

Formation

Green diamonds get their color mainly from natural irradiation. This irradiation occurs when diamonds lie underground for millions of years near radioactive minerals such as uranium or thorium. The radiation penetrates the diamond and changes the structure of the crystal lattice, causing certain light waves to be absorbed and the diamond to appear green.

The intensity of the green color depends on the duration and intensity of the radiation, as well as the depth of penetration into the diamond. Green diamonds are extremely rare, especially those with an evenly distributed color, making them highly sought after on the market.

Overtones

In addition to intensity, overtones also have a decisive influence on color perception. Due to the wide variety of overtones, every green diamond is truly unique. The most common overtones are yellow, blue, brown, and gray.

sources

Natural green diamonds are extremely rare and can be found in various regions around the world. However, there is no specific region known for high production. Since green diamonds are created by natural radiation, their deposits are not limited to specific geological formations, but can occur anywhere where the necessary conditions have been present for millions of years. Some of the most significant locations are:

South Africa: Known for a variety of diamonds, including green diamonds, due to the rich geological conditions.

Brazil: Some of the most notable green diamonds have been found in Brazil, which is known for its variety of mineral resources.

India: Historically, India has produced some famous green diamonds, although modern finds are rarer.

Russia: due to the well-known sanctions, we do not currently offer diamonds of Russian origin: But diamond mines in Siberia have also produced green diamonds.

Prices

A high-purity NF Green diamond can be expected to cost between CHF 50,000 and CHF 90,000 per carat. For a fancy intense/vivid stone, the price rises to at least CHF 150,000 per carat.

Blue diamonds

Formation

Fancy Blue diamonds get their color mainly from the presence of boron in their crystal structure. Boron atoms alter the way light is refracted through the diamond by absorbing mainly red light waves, giving the diamond its blue color.

How does this happen? The element boron enters the Earth's mantle via subducted oceanic plates and is incorporated into diamonds, which are later found in mines that are geologically linked to these processes.
Proximity to oceans or their former crusts is therefore a decisive factor in the occurrence of blue diamonds.

The intensity of the blue color depends on the amount of boron present. Some of the most famous blue diamonds, such as the Hope Diamond, display an exceptionally deep blue color, which is due to a higher concentration of boron.

Overtones

Blue diamonds without overtones are a real rarity. Most blue diamonds have a gray overtone, and often a green one as well. Natural blue diamonds without overtones are the most valuable.

sources

Blue diamonds are extremely rare and are mainly mined in certain regions of South Africa, particularly in the famous Cullinan Mine, which has produced some of the world's most famous blue diamonds.

Cullinan Mine, South Africa, Canada,

Golconda region, India: Historically, mines in the Golconda region have produced some significant blue diamonds, although these mines are no longer in operation today.

Australia: The Argyle Mine has produced some blue diamonds.

Prices

An NF Blue diamond with high clarity can be expected to cost between CHF 180,000 and CHF 350,000 per carat. For a stone with fancy intense/vivid color, the price rises to at least CHF 400,000 per carat.
