Myths and legends

What is the most expensive diamond in the world?

To describe and record the spectrum of colors of such diamonds, a formula of fancy color and its intensity is used. It looks like this:

Fancy / Intensity / Overtone / Color , where
Fancy – denotes a fancy color and is always indicated for all such diamonds;
Intensity – intensity or density of color perception, the scale will be given below in the text in the section “Palette, rarity and intensity”;
Overtone – overtone, a general name for shades, overtones and subtones. This parameter describes the presence of a second, third and even fourth color in the stone, if any. If there are none and the stone has one distinct color, the overtone is not indicated.
Color is the main intense color of a diamond, which the human eye perceives immediately without looking at it.

Live example:


Fancy Deep Brownish Yellowish Orange or Fancy Deep Brownish Yellow Orange, where:

Deep – deep rich color;
Brownish – light brownish tint;
Yellowish – light yellowish tint;
Orange is the primary orange color.

The importance of purity and cut quality in such stones also plays an important role, although not as noticeable as with colorless diamonds. Still, in fancy diamonds, color comes first.
However, if the diamond is of a rare color and at the same time perfectly clean and perfectly cut, this is a direct route to auction.

Palette, intensity and rarity

  • Orange;
  • green;
  • magenta (violet);
  • cyan (blue);
  • pink;
  • red (about 300 diamonds of this color are known).
  • Fancy Light is a weakly expressed color, but it is there and the eye can catch it with other light sources;
  • Fancy is a moderate color, the average person will confidently say: “this diamond is exactly this color.”
  • Fancy Intense – intense color.
  • Fancy Vivid is a distinct, rich color. In most cases, the rarest and most valuable intensity;
  • Fancy Dark – dark color, as if a dark film was placed on top of the main color;
  • Fancy Deep is a deep color, very rich and dense, but with a dark tone.

Below I will go into more detail about each key color and its intensity.

Yellow

The yellow color of diamonds is due to the presence of nitrogen in the structure of a particular crystal.
Nitrogen molecules absorb the blue part of the visible color spectrum, thus giving the diamond its natural yellow color.
The more nitrogen in the stone, the richer and more intense the color.

  • Faint yellow (UV) – pale yellow, very faint shade;
  • Very light yellow (WX) – very light (or slightly) yellow;
  • Light yellow (YZ) – light yellow, quite visible.

Below are live video examples:

The degrees of saturation are given below. Fancy Vivid is the most expensive, priced from $7000 per carat.

Below is a live example:

Like all fancy diamonds, green ones come in thousands of different shades. Pure green is extremely rare and costs between $7000-10000 per carat for a fairly mediocre stone. It is more realistic to find green with a brown or yellow tint.

Green diamonds are no exception in terms of color saturation. The brighter the color, the more expensive the stone. The intensity scale is shown below.

Live examples:



Diamonds with a pronounced blue color are extremely rare, they usually come in blue-gray and blue-green colors.
The presence of boron in the crystal lattice of such diamonds is the main reason for their blue color. The presence of hydrogen is responsible for the gray color, and excessive radiation is responsible for the green color.
Blue diamonds form deeper than all other stones. Mining takes place in only two places on the planet – the Cullinan mine in South Africa and the Argyle mine in Australia.

Degrees of saturation and mixing options for blue, green and gray colors.

The average price per carat of a blue diamond is 500-700 thousand US dollars.

Famous blue diamonds.

Both of these colors are extremely rare and extremely rare as a base color in stone. Basically, they act as moderating colors, creating a certain shade of the diamond. Typically this is blue-gray for violet and pink for magenta. The combinations turn out to be incredibly beautiful.

Diamonds of this group are mainly mined at the Argyle deposit in Australia, although finds have also been found in Yakutia and Africa.

The violet and purple color is due to the presence of hydrogen in the crystal lattice. Although there is still no clear explanation for the nature of these colors.

Prices start at 70 thousand dollars per carat. However, stones larger than 1 carat are extremely rare.

The author was lucky in his life to see only one pink-purple diamond larger than one carat.

Scientists gemologists still do not have a single clear position on the nature of the pink color in diamonds. So far, the main version is that the pink color is due to a modified crystal lattice in diamond crystals, which POSSIBLY explains this color.

Due to the very deep formation of pink diamonds and the high likelihood of plastic deformation, it is extremely difficult to find pure pink diamonds without inclusions. As a rule, in most cases, ready-made stones have SI-I clarity.

Prices start at $30 per carat.

The most famous red diamond — “Moussaieff Red”
This is a perfectly clear Fancy Red Internally Flawless diamond weighing 5,11 carats. Bought at auction by its current owner Moussaieff Jewelers Ltd. for US$8 million in 2002. The original diamond was found in the 90s in Brazil. There is no current estimate of value.

Finding a fancy-colored diamond is a great success for the miner, because the sale of one such stone can cover the cost of mining hundreds of carats of ordinary colorless diamonds (although there are VERY rare crystals among them, but more on that in another article).
Colored diamonds are much less likely than colorless diamonds to be pure without inclusions. By and large, non-white color in diamonds is an anomaly, a defect in the crystal lattice. Such defects “attract” other minerals during crystal growth, which results in an impure diamond crystal. Therefore, finding a pure colored diamond is even greater luck than finding it in the first place.

Cutting

  • Diamonds are almost always NON-round;
  • The cutting of such stones is often imperfect.

In addition, the round cut reflects most of the light falling on the stone, while fancy shapes allow the natural color of the diamond to be more deeply conveyed.

However, if a diamond has perfect symmetry, proportion and polish, then its price increases greatly. And it looks very cool as in the video below.

In other words, the better the stone is cut, cleaner, larger and has a rarer rich color, the more expensive it is.
You can learn to navigate the real prices of colored diamonds only through extensive practice and experience.
However, only colored diamonds truly have investment potential.

Since 1722, it has been considered a family jewel of the Bavarian Royal House of Wittelsbach, until Ludwig III was forced to abdicate in 1918.

Bavaria became a republic, and the king’s property was transferred to a special fund. The heirs were paid money, but due to inflation they all “burned out.” The state sold the jewelry, including the Wittelsbach diamond (35,56 carats).

In 1931, it appeared at a Christie’s auction, where it was bought by a certain Thorpe for 56 thousand pounds. But there is a version that the price did not suit the auction organizers, and they never sold it.

The diamond itself disappeared, leaving only its copy. It was later discovered by chance by a jeweler in 1962. It was remembered in 2008, when Christie’s put it up for sale again, and it was bought by Lawrence Graff, a famous jeweler, for $24311190.

Pink Star, $71

Then the stone became the property of the Bourbons, but during the revolution the treasury was plundered and famous diamonds disappeared.

In 1828, Pavel Demidov bought it for 80 thousand pounds, in 1865 he gave it to Jijiboy Jamsetji for 100 thousand pounds, who, in turn, resold it.
