Created deep down inside the earth, every diamond is a wonder of nature, telling a story spanning millions of years. The light reflected in a perfectly cut diamond is of breath-taking beauty. At Beyer, we process only those stones that meet the highest quality standards. That is why we only buy diamonds graded as Triple Excellent by the Gemological Institute of America (GIA), which means that the cut grade, symmetry and polish meet the highest possible quality standards and the GIA report number is laser-inscribed into the girdle.

No other gemstone better epitomises eternity, strength and perfection, which is why the diamond is the ultimate symbol of love and a popular engagement gift. We would be delighted to advice you on your choice of diamond and to design your own personalised piece of jewellery with you – a timeless jewel that will accompany you throughout your lifetime.

When purchasing a diamond, pay attention to the five Cs:

The weight of a diamond is measured in carats. One carat is equivalent to 0.2 gram. A diamond’s value depends on its size, but only in combination with the other so-called “Four Cs”. Anyone who also regards diamonds as an investment should look at stones weighing at least 1.01 carats. This additional 0.01 carat ensures that if the stone is subsequently subjected to further processing, it does not drop below the “magic weight” of 1 carat and thus drastically depreciate in value.

Highly fine white diamonds are extremely rare. Most stones are almost colourless, with tints of yellow. The colour scale defined by the Gemological Institute of America (GIA) extends from D(absolutely colourless) to Z (light yellow). For reasons of quality, the classic brilliants we use are graded D-H. Stones in this category are regarded as white diamonds, and are therefore very rare and valuable.

The greater the clarity of a diamond, the rarer and more desirable it is. Clarity is measured by examining under 10x magnification the existence of internal flaws, or inclusions, which occur during the natural formation process. The Gemological Institute of America (GIA) uses 11 clarity grades, ranging from Flawless to Imperfect. We select exclusively diamonds graded between Flawless and SI1 Slightly Included on the clarity grading system. SI1 inclusions are not visible to the naked eye.

Cut denotes the balance of proportion, symmetry, cut and polish of a diamond. Only a perfectly cut diamond reflects the white light that falls on it back and forth from one facet to another so that the whole rainbow of spectral colours is visible, giving rise to flares of colour known as “fire”. The GIA Cut scale ranges from excellent to poor. A diamond whose cut grade, symmetry and polish are of the highest quality is described as Triple Excellent. When crafting jewellery with classic brilliants, we only use stones of this grade.

We solely purchase diamonds from countries that have signed the agreement known as the Kimberley Process. Furthermore, we know many of the diamond cutters personally. In this way, we can guarantee that no illicit diamonds find their way into our workshops. Confidence also refers to our many years of experience and care in handling inimitable diamonds. After purchase, we can, on request, also regularly clean the stones or check the settings to ensure that they lose nothing of their original splendour.
