A diamond’s beauty often
leaves us lost for words. But it can be perfectly expressed in exceptional jewellery.

A desire to convey this timeless elegance is the driving force behind our passion. Blesq diamonds are extensively examined, cut to perfection by experienced master craftsmen and transformed into one-of-a-kind jewellery. With artistic flair, we highlight the specific essence of every single diamond – so that your chosen diamond is a truly sensory experience.

Origins

Timeless relics

Cutting and refining by Blesq

Blesq only works with certified and ethically produced rough diamonds. They are sourced exclusively from countries that respect the requirements of the Kimberly Process and oppose the trade of conflict diamonds.
So we can promise you that every Blesq diamond is sustainably produced and meets the highest ethical and quality standards.

Every single diamond is a natural wonder. 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. That is why we trust only the most experienced and best diamond cutters to tackle this most impervious of natural materials and bring forth masterpieces, whose countless refractions will make your eyes shine. The cut determines the brilliance and intensity of the diamond’s glittering lustre, in which all the colours of the rainbow come to life. The real art lies in distilling the original character of the rough diamond in the cut and finished form. This is the only way to produce an irreplaceable diamond with its own unique charisma – which you can fall in love with, time and time again.

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.
