value of a diamond

diamond grind

Many criteria determine the value of a diamond and therefore the price: Cut, Colour, Clarity and Carat.

No diamonds are alike, even if they seem identical to the naked eye. You have to
4 C and the possibilities of their combination to know to understand why two jewels of the same size can vary quite significantly in price.


Only the well-proportioned cut gives the diamond its unique glow.
The cut is the criterion that the person can directly affect-others, the nature
specified for each stone.
A good cut reflects the proverbial fire of diamonds with proper proportions and
the arrangement of its facets (surfaces that reflect light at certain angles).

It is important to distinguish the purely mechanical process of grinding on the shape of the diamond.
The choice of form is subject to personal taste. Very popular is the round brilliant cut,
frequently are also emerald, pear, princess cut and marquise and heart or Navette.

In a cut diamond with good proportions, light is reflected from one facet to another and can radiate
then through the upper part of the stone back. If the cut of the diamond is too pointed, light rays escape through
the lower part of the stone. The cut is too shallow, the light beam on the upper part is refracted back into the interior
and escapes through the lower part of the stone.


The weight and thus the size of a diamond is measured in carats.

1 Carat = 0.20 g

The carat is divided into 100 points. A diamond of 50 points weighs half a carat ie.
Two diamonds of equal carat weight can still vary in their price, because very
their quality and value will depend also on their cut, color and purity.


color of the diamond

Color is the most personal subjective criterion within the 4 C, as judged preferable to any other color of a diamond Farbtöne.Die Graduiereung for the measure, ie how
he will close the colorless kommt.Die Seltendsten graduated with "D", "E", "F" and "G".
The majority of the diamonds is white to slightly tinted white and they are graded with "H" to "L".
Yellow diamonds have visible tint to graduation "M" or lower.

Purity of the diamond

Clarity A diamond's clarity.

The purity is recognized in the extent to which it is free from inclusions of non-crystallized carbon, the substance from which it arises.
Often inclusions with the naked eye can not be seen and only at much magnification they are seen.
The purer the diamond, the rarer and more valuable
