Diamond Guide



At Jewellers Workshop we pride ourselves in being diamond experts, and as such we take the utmost care in ensuring all diamonds that we select are of exceptional quality.



4 C’s 



The cut grade of a diamond refers to its proportions, symmetry and finish. The better the cut of a diamond the more fire, brilliance and scintillation it will display; or simply put, the more it will sparkle. At Jewellers Workshop we believe that cut is the most important factor to consider when purchasing a diamond, after all, the allure and beauty of a diamond is in it’s sparkle! For this reason we take time and care in only choosing diamonds with top cut grades to ensure all Jewellers Workshop diamonds display their full beauty.

For those seeking true perfection we are proud to offer Passion8 diamonds, our premium range of diamonds that display eight perfect hearts and eight perfect arrows.





The colour grade of a diamond refers to the presence, or lack of, colour within the stone. Diamonds are graded from ‘D’ being colourless through to ‘Z’ being light yellow. At Jewellers Workshop we offer predominantly D-H colour for the most colourless look in your jewellery.

Beyond the D-Z colour spectrum, there are fancy coloured diamonds. For those seeking something brighter, we carry a small range of exquisite coloured diamonds, and can source more on request.






Almost all diamonds have inclusions, these are imperfections within or on the surface of the diamond that develop while they are being formed in the ground, and are unique, much like a finger print.

There are 11 possible clarity grades that are awarded based on the density, colour, size and positioning of these inclusions as inspected under 10x magnification. These grades range from ‘flawless’ which is extremely rare and means that there are no inclusions visible under 10x magnification, through to ‘included’ meaning the inclusions are visible to the naked eye.





Probably the most well known of the four C’s, carat is a unit of measurement used to weigh diamonds. The most common misunderstanding when looking at the carat weight of a diamond is that it can be used to judge the size of a diamond. This is where considering the cut of a diamond in conjunction with its carat weight is important. If a diamond is cut with proportions that are deeper than ideal it will not only look dull, but will also appear smaller than other diamonds of the same carat weight of ideal proportions. Diamonds that have proportions that are shallower than ideal will appear larger in diameter than their well cut counterparts, but will lack presence as their cut allows them to leak light.





Diamonds come in a variety of different shapes, and are a great way to express your individual style. Below are a few of the most popular examples of different diamond shapes.
