THE PLAY OF LIGHT OF DIAMONDS

Genuine, well-cut diamonds sparkle in an irresistible way and cast a spell on the viewer with their play of light.
Rarities and unaffordable goods have a fascinating effect on us humans. The rarer something is, the more we want to have it. No wonder that diamonds are among the most sought-after luxury goods in the world.


The value of a diamond is measured according to a scale of the Gemological Institute of America (GIA) and is composed of the four C's: Carat, Clarity, Cut and Color.

DIAMONDS - Tough stones

Diamonds are the hardest natural substance we know.
Diamonds were formed millions of years ago and under scorching heat and strong pressure deep in the earth's interior. Carbon atoms join together to form a solid crystal lattice and thus form the rough diamond.
These tough and translucent gemstones have an exceptionally strong luster and high refraction. This is called the fire of diamonds.

Very few diamonds are colorless. Mostly they are slightly yellowish to intense yellow, over orange to brown or gray. Even inclusions are not defects, but by nature built-in certificates of authenticity. Due to its extreme hardness and toughness, most stones are used in the industry for grinding, drilling, milling, etc. Only a small part of the diamonds are suitable for jewelry purposes, but then they sparkle all the more beautiful.

THE CUT

An important beauty factor of a diamond also depends on its cut. Rough diamonds do not look like the polished and cut gemstones we know. This is created only through the time-consuming process of cutting.
A brilliant describes a diamond with the special brilliant cut, which is characterized by high brilliance. The most common types of facet cuts in diamonds, consisting of a multitude of small surfaces, are for example:

  • - the mentioned brilliant cut
  • - the heart cut
  • - the marquise cut
  • - the octagonal cut
  • - the drop cut
  • - the princess cut

PROPORTIONS

A diamond only really sparkles when its proportions are right. A perfect cut reflects incoming light as often as possible inside the diamond and throws it back to its surface.

CARAT

The carats can be determined by the size of a well cut round (brilliant cut) diamond. The larger the diameter, the higher the carat number, depending on the cut of the diamond.

ø 11.2 mm =   5.00 ct.
ø 9.5 mm =   3.00 ct.
ø 8.2 mm =   2.00 ct.
ø 7.3 mm =   1.50 ct.
ø 7.0 mm =   1.25 ct.
ø 6.5 mm =   1.00 ct.
ø 5.8 mm =   0.70 ct.
ø 5.0 mm =   0.50 ct.
ø 4.1 mm =   0.25 ct.
ø 3.0 mm =   0.10 ct.

CLARITY

Diamonds are products of nature and therefore not 100% pure. Everything depends on the strength of the magnification. A diamond can be called flawless when the eye cannot see inclusions or defects at a tenfold magnification.

if internally flawless
vvs      very, very small inclusions
vs very small inclusions
si small inclusions
p1 Piqué 1 difficult to see with the eye, does not disturb the brilliance
p2 Piqué 2 easily visible to the eye, slightly disturbing the brilliance
p3 Piqué 3 very easily visible to the eye, disturbing the brilliance

COLOR

Diamonds are not only colorless, but also come in various colors. Natural diamonds with colors of high saturation are extremely rare and are called "fancy colors". Yellowish or brown diamonds are comparatively much more common.

The rare colorless diamonds are recorded together with the yellowish diamonds on the so-called "yellow row" color scale.
