Diamond Baskets Based on the investor's personal preferences regarding investment amount, holding period and return, an individual Blesq-Diamond basket is created. This basket contains exclusively GIA certified diamonds in various cuts from 1.0 to 5 carats in the colour D as well as clarity FL/IF and with a proven excellent cut.

The diversity can be further increased if diamonds of the colours E & F and the clarity VVS1 to VVS2 are also integrated into the portfolio. These diamonds are also used in the jewellery industry and can therefore be sold at shorter notice. Upon request, the individual Diamond Basket can be diversified with colour diamonds (Fancy Diamonds).

In the Blesq Boutique you can examine a selection of investment grade diamonds starting at 1.0 carat in the classic cuts.

Fair mining and trade: strict protective measures for people and the environment.

Origin Diamonds are formed deep inside the earth's crust, up to 600 kilometres underground - like mythical creations in a Jules Verne adventure. Under enormous pressure and at temperatures of up to 1,500 degrees Celsius, carbon is transformed into rough diamonds. However, they can only be discovered if they are transported to the accessible top layers of the earth's crust by massive magma eruptions in volcanic vents, or through many centuries of continuous tectonic processes. By the time a diamond reaches the light of day, it may already be several billion years old.

Once you know about this extraordinary process, you don't even need to have seen a diamond to be captivated by these precious stones. The word diamond is derived from adámas, the Greek word meaning 'invincible'. It is this unparalleled hardness that gives the diamond its name and makes it so extraordinary.

Carat, Cut, Clarity, Color Each diamond possesses a unique character, in where his fire lay, divine history, development, and mastery. To objectify these rare unique items for trade and investment, in quality and value, the famous 4 Cs have been judged since the 1940s.
Carat, Color, Clarity, & Cut.
Carat - describes the weight of a diamond and significantly decides his value. 1 carat equals 0.2 grams, with larger stones being scarce.
Color is certified from weak pastel shades " Faint " to " Fancy ", exceptionally rich in color.
Only when light breaks into in the colored diamond, can we guess what radiation he absorbed millions of years ago within the earth's interior. The color quality of white and yellow stones is judged by means of an international scale from D "colorless" to Z "light yellow".
Clarity - is crucial for its brilliance, thus defining the fire of the diamond. The clearer his purity, the more he can sparkle. Inclusions, during the creation process, give him his unique recognizeable characteristics. They are called "clouds", "spots", and "feathers" for example, which are documented under 10x magnification. There are divisions of flawless diamonds with the acronym FL for "Flawless" to P "Piqué".
Cut - is the master's handwriting whos hands he has traversed. Each cut depends on the personality of the diamond, and must be perfectly tailored to follow. Only then can his carat be preserved, and his unique beauty worked out. The cut, is a supreme discipline that completes the diamond in all its brilliance.

Certification Authenticity, transparency and expertise, are for us, the basis of every trade, therefore including the 5th C - Certification. All of our investment diamonds are certified by the GIA. The Gemmological Institute of America has been specializing in the certification of diamonds since 1931 and protects the gemstone trade as an independent, non-profit organization. For each investment diamond that passes through our hands, you receive a GIA certificate that reliably and internationally acknowledges the quality and value of your diamond.

What does "Color" mean?

The presence of rare hues makes diamonds particularly valuable. White, colourless diamonds, for example, are classified according to a broad spectrum from D (colourless) to Z (light yellow) – whereby colourless is considered rare and particularly valuable and yellow tones are more common and slightly less valuable. The value of fantastic colour nuances like pink, blue, orange, green or red are determined independently of this spectrum. Instead, they are individually evaluated according to their intensity and alluring depth of colour.

What does "Carat" mean?

The weight of diamonds and all other precious stones is measured in carats – one carat is equivalent to 0.2 grams. While in the Middle Ages and in ancient times precious stones were weighed for trade using scales counterbalanced with stone weights, these days specialists use highly sophisticated measuring technologies that are accurate down to one hundredth of a decimal point. Such absolutely precise weight specifications are essential, given that every milligram of diamond is unique and precious.

What does "Clarity" mean?

Clarity indicates the extent to which a diamond is free from inclusions. Diamonds are formed in extreme heat and under enormous pressure – far below the earth’s crust. This very organic process means that almost all rough diamonds contain inclusions or surface imperfections. Cut diamonds that no longer exhibit any of these characteristics are considered particularly pure and valuable. The degree of clarity ranges from FL (flawless: free of inclusions and external marks) to I (imperfect: large, numerous, easily identifiable inclusions and marks).

What does "Cut" mean?

The cut has a significant impact on a diamond’s brilliance: only a perfect, symmetrically balanced expert cut can create that magical, legendary glittering effect. This highly individual and brilliant sparkle, through masterfully chiselled facets, requires great skill and experience – it requires Blesq expertise.

How are "natural fancy colour diamonds" classified?

Rationally identifying and grading such natural wonders may seem like an impossible task; however, a range of specific varieties have already been established. The Geological Institute of America (GIA) developed a special colour grading system to precisely classify the quality of natural fancy colour diamonds. The 4Cs (cut, clarity, colour, carat) are taken into consideration; however, the value is overwhelmingly determined by the individual strength and purity of the colour. The GIA colour grading system focuses on the colour, tone and intensity to determine an exact classification. The system also incorporates the respective depth of colour in the differently coloured diamonds. This is necessary, because yellow diamonds (for instance) come in many different colour intensities, whereas blue diamonds do not.
