Diamond Information

The 4 Cs

Diamond are sold by carat which is a unit of weight.  One carat is equivalent to 0.2 grams.

 Generally as carat size increases because the larger the diamond the more rare it is. As the price of diamond increase with carat weight the actual size does not the cut of the diamond can dertermine the actual value.

A deeply cut Diamond has a greater proportion of toal weight as the deeper cut means the Diamond has a larger "hidden" weight then a Diamond with larger diameter  making it appear larger.


Our Craftsmen  source the Diamonds straight from the manufacturers and so are able to provide you witwith Diamonds that are of highest quality at affordable prices.

The most important feature of the Diamond is the Cut or Shape. This determines the Diamonds sparkle; without  a high cut grade even a Diamond of high quality can appear dull and lifeless. A Diamonds Cut grade is about how well a Diamond facets interact  with light. This requires great artistary and workmanship. A Diamond cut will play a major factor in determining  its beauty and value. The GIA Diamond Cut scale for Roubd Brilliant Diamond range from D-Z grading of excellent to poor. To maximise your budget, choose the highest Diamond Cut grade your budget allows. We suggest a cut grade of Very Good or better.


The highest quality Diamonds are colourless, while those of lower qualityhas noticeable colour. The GIA grade the Diamond colour on a scale of D (colourless) to Z (light yellow( D -Z. D is know White Diamonds, it is also the most devoid of colour anand very rare. Whereas G and H are near colourless and these are lower priced making them excellent value for money.


Clarity is the assessment of small imperfections on the surface and internally. The surface flaws are called blemishes and internal defects are known as inclusions. These imperfections are not noticable and do not effect Diamond beauty, however the Diamonds with least and smallest inclusions recieve the higest grading.

The 4C4Cs distinguish the quality of the Diamonds. It is the universal method of assessing the quality of the Diamonds. 

Diamond clarity has 6 categories:

Flawless - No inclusions/ blemishes identifiable by assessment from a skiled grader.

IF - (IF) Internally Flawless No inclusions or blemishes visible under 10x magnification.

Very Very Slight Inclusions (VVS1 & VVS2) Inclusions are so slight they are difficult for a skiled grader to see under 10x magnification.

Very Slightly (VS1 & VS2) Inclusions are observed with effort under 10x magnification but can be characterised as minor. 

Slightly Inclusions (SI1 & SI2) inclusion are noticeable under 10x maginification.

Included (I1, I2, I3) - inclusions are obvious under 10x magnification which may affect transparency and brilliance.
