The value of a diamond is determined by the 4 C's :  Cut , Colour ,  Clarity  &  Carat .


Cut :
This has considerable overall impact on the appearance of the stone. We use only Ideal or Fine Cut Diamonds . 


Color :

Diamonds are found in a range of colour, from white towards yellow. The less yellow there is, the higher the value. The most valuable diamonds are totally clear. All our diamonds are H or above H color (I only if clients wish).

Generally speaking unto H , diamonds are considered to be of good quality and good 'whiteness'


Clarity :

Clarity is a measure of how much and how many inclusions there are in the diamond. Every diamond that you will see has some sort of natural 'fingerprint' in it. Inclusions are natural as diamonds are mined and not manufactured. Never the less, the fewer the inclusions, the more valuable the diamond. Our diamonds are unto VS2 (SI1 only if clients wish).

Generally speaking unto VS2, diamonds are considered to be of good quality and good clarity.

Carat :
Carat weight refers to the weight of the diamond, not the size. By definition 1 carat is exactly 200 milligrams. Large diamonds are more rare than small diamonds so the diamond value tends to rise exponentially with carat weight. The carat of the stone will be dictated by your tastes and preferences.




Established in 1931, Gemological Institute of America GIA is considered to be the world s largest and most
respected nonprofit institute of gemological research and learning. The GIA conducts courses in gemology and runs trade laboratories, the World’s Most Trusted Name in Diamond Grading and Gemstone Identification.

The following terms and tables are recognized by the GIA :
COLOR - The color of a gemstone is important because it is visible to the human eye.
COLOR GRADING - Diamond coloring is graded by comparing it to a set of master stones that have been certified by the appropriate organization.
CLARITY - This term refers to the number and size of inclusions present in a cut diamond.
WESSELTON - Is a mine that only produced one color grade that was better than top grade. Wesselton can be applied to any very slightly tinted stone.
