The 4Cs

In the 1940s, GIA established the 4 C’s and the International Diamond grading system —  to this day, the worldwide standard for evaluating diamond quality.

Before purchasing any diamond, it is necessary to have all the information available to make the right decision. 

This craft began in 1471 in Bruges and is a highly skilled job which involves cutting down from the original uncut diamond to smaller pieces suitable for jewellery use. The cut refers to the proportions, symmetry and polish of the diamond, which the beauty of the stone highly depends on. The diamond cut has three main effects on appearance, the brilliance (which is the way that the light reflects inside and from the stone), the scintillation (the sparkle!) and the fire which is the dispersion of light. All of these factors play an important part in how the diamond is perceived by the eye.

Diamond carat weight is the measurement of how much a diamond weighs and not how large it is, as many people think. A metric 'carat' is 200 milligrams. It is important to consider cut and carat together as a high carat diamond might not necessarily have the best cut. Our expert can help you with choosing the best diamond for your budget.

Most diamonds contain some inner flaws due to the nature of their creation. The visibility, number and size of these inclusions all determine the clarity. This is assessed under 10x magnification and the clearer the diamond, the more premium it then becomes.

Flawless - No inclusions or blemishes when viewed under 10x magnification by a skilled grader
Internally Flawless (IF) - No inclusions, only blemishes when viewed under magnification
Very Very Slightly Included (VVS1 & VVS2) - contain minute inclusions which are difficult for a skilled grader to see under magnification
Very Slightly Included (VS1 & VS2) - contain minor inclusions that range from difficult (VS1) to somewhat easy (VS2) to see under x10 magnification by a skilled grader
Slightly Included (SI1 & SI2) - contain noticeable inclusions that are easy (SI1) or very easy (SI2) to see under 10x magnification
Included (I1, I2, I3)  - contain inclusions that are obvious under 10x magnification. 

The colour of a diamond is important and they come in a wide variety. White diamonds are rated on a scale from D-Z with D being the clearest. However D & E colour rated diamonds are very rare. G-H are usually the best value without compromising too much on the colour. All of these factors must be considered in finding the perfect diamond for your jewellery.
