In this Diamond Education section, you will find that your questions about diamonds and their characteristics will be answered.

The ColourClarityCut and Carat Weight of a diamond are collectively termed the 4Cs. These are the factors that, when combined together, define a diamond’s quality and ultimately determine its value. The Gemological Institute of America (GIA) created these 4Cs of diamond quality, which has become the universal method for assessing the quality of any diamond. The creation of the 4Cs means that diamond quality can be communicated in a universal language so that as a buyer you know exactly what you are buying.

The brilliance and fire of a diamond is determined by the diamond cutter's skill and craftsmanship. When a diamond is cut to the highest standard, the more sparkling and dazzling your diamond will be.


The shape of a diamond is probably the first consideration when buying your diamond. Personal taste will guide you towards the shape that excites you and all have contrasting and beautiful qualities. The diamond's formation is described as viewed from above the stone ~ such as round/brilliant cut, princess cut, pear cut, emerald cut.

Diamond of different colours compared side by side


Today, we can choose from a myriad of coloured diamonds. The higher quality grades are usually given to those stones with a characteristic of little or no colour. Again the diamond that completes your piece of jewellery will be determined by personal taste.

Diamonds contain clarity characteristics called inclusions or blemishes. Inclusions are enclosed within the gem and blemishes are on the surface of the diamond


Completely perfect diamonds are rare, but these diamonds will receive the highest grade for clarity. Virtually all diamonds have small imperfections, but these tiny blemishes do not detract from the diamond's beauty.


Carat weight is a familiar term to most of us and is significant along with the other fundamental determinates as to a diamond's value.
