colored diamonds

In the case of colored diamonds, it is important that the coloring is of natural origin. In addition to the usual criterias and above all, the color intensity plays a major role. The most precious colored diamonds in the world may have inclusions, which actually can give the diamond a special touch.

One of the best-known diamonds covered with inclusions is the 32-karat "KOI Diamond", named after the Japanese Koi-fish. Found in the Congo and initially classified as an industrial diamond, its weight In the raw state was over 60 carats.

It was found in Diavik, Canada's Northwest Territories, which is about 135 miles away from the Arctic Circle, in October 2018. It can already be said that the diamond will receive the color classification Fancy Yellow. The estimated value depends on the cutting and the result it ends up.

diamonds as an investment

Not every diamond is suitable for investment purposes. High-quality diamonds are excellent for capital protection. Also medium to long-term high growth rates can be recorded. By high quality is meant heavyweight colorless, preferably flawless and very rare colored diamonds.

Not every dealer or jeweler is getting access to such special heavy weight diamonds or those who are very rare by their color. Surprisingly, among the dubious are some jeweler chains which have a well-known name to the outside, but from the inside, some of them operate very suspicious and dishonest. Even on television the audience is pulled over the table. Be cautious of teleshopping channels such as "Juwelo" or "QVC"!

counterstrike of truth

If you shut the truth and bury it into the ground, it will only grow and accumulate so much explosive power that on the day it breaks through, it will sweep away everything that stands in its way. Emile Zola, French novelist of naturalism

the only reliable certificates

acknowledged worldwide

Even today, diamond dealers in Germany, who sell diamonds in seals, are attributed to the "gray capital market". A misleading of incompetent and hypocritical foundations.

The truth is, when buying a diamond, to make sure the diamond is certified and sealed. Never buy jewelry or diamonds with certificates issued by the jeweler himself.

It has already happened that especially colored diamonds received different ratings not only from different companies but also from the same gemmological laboratory. This is simply because different indivituals verified the diamonds and each has a different view of color or purity rating. Thus, a certificate does make sense, so that one has the the certainty that the diamond is not in any form synthetically treated or of such origin. Regarding the color, it is the own eye and personal assessment, both the customer's and the competence, the specialist knowledge as well as the experience of the respective retailer, what matters.

Red is the rarest naturally occurring color. As with the pink diamonds, it is believed that the red glow is due to a deformation of the diamond crystal lattice.

The 2.11 carat EVERGLOW is the heaviest and largest of its kind in the history of the Argyle Tender.

Also the fine blue diamonds are maginificent. The bluish color is caused by a proportion of boron atoms, which replace the carbon at some positions of the crystal lattice. As a result, light absorption occurs in the visible range of the electromagnetic wave spectrum, more specifically in the yellow wavelength range, the complementary color of blue.

Extremely rare and most beautiful. It is said that diamonds are the (joy) tears of God ...

The 59.6 carat Pink Star is the largest "Internally Flawless Fancy Vivid Pink" Diamond and is one of the greatest natural resources on earth. It was sold for 553 million Hong-Kong Dollars (71.2 million US-Dollars) in 2017. It is the highest price ever paid for a diamond.

The "Pink Star" was unearthed in 1999 by the mine operator De Beers in South Africa. In the raw state, its weight was 132.5 carats. To reach its present value, the diamond was cut and polished for two years by the company Steinmetz Diamonds. The Entrepreneur named the gemstone "Steinmetz Pink", as this was presented to the public in 2003. Four years later, the diamond was traditionally renamed to its present name by its first owner.

Above and beyond Vivid

The 0,47 carat "Bermuda Triangle Diamond" is the worlds only diamond ever declared as NATURAL FANCY EXCEPTIONAL LEMON GREEN, unearthed in the early 90´s, certified by the International Gemological Institute in Antwerp, Belgium.

Estimated value is more than a Million USD, resulting of its unique classification, intense coloring in combination with a triangle cut and very high clarity.

Green diamonds are extremely rare by nature. The most famous is the "Dresden Green Diamond" with a weight of 41.70 carats. It is located in the Albertinum Museum in Dresden, Germany. Natural colored green diamonds are mostly to dark olive green, yellowish or only very light in their green color. Often, inclusions are also visible to the naked eye. The Bermuda Triangle Diamond, on the other hand, is radiant green like no other green diamond found so far, which is why it was given the "EXCEPTIONAL" classification, ranked in the rating even above the actually highest classification "vivid".

Comment from Forevermark of the De Beers Group: "Exceptional Diamonds are kept separate from other diamonds from the moment of discovery. Their carat weight, colour and purity classify them as extraordinarily valuable and rare. Of all the polished diamonds that come from the rough diamonds mined by the De Beers Group of Companies, only one in millions can be become a polished exceptional diamond. They are truly in a class of their own."
