4 C's of a Diamond

Posted on the 28th November 2014

We thought we would educate you today on the 4 C’s you need to know about when purchasing a Diamond. There is a lot to consider when making such an investment, whether you keep it as a stunning loose gemstone or make it into a bespoke creation just for you, make sure you know exactly what you’re looking for…and talking about. CUT The cut is often simply thought of as the shape of the Diamond, but when it comes to grading stones, cut actually refers to the quality of the cut, including proportions, symmetry and polish which all influence how well that stone will dazzle and sparkle. With a perfect cut, the Diamond will allow the maximum amount of light that enters through its top to be reflected and dispersed back through all of its facets, making it twinkle like a star! Popular styles of cut are brilliant cuts, because they allow maximum sparkle and brilliance (hence the name). Have look at our impressive Diamond jewellery collection CLARITY Most Diamonds have tiny birthmarks called ‘inclusions’ which interfere with the light entering and leaving the stone. They come in many forms, such as little black marks, feathers or clouds under the surface of the stone. The term "Clarity" refers to the presence or absence of these tiny inclusions within the stone and/or on the surface. GIA’s clarity grading system goes from Flawless (IF) to Included (l), and is the most widely used in the industry. Ideally everyone wants a Flawless Diamond (myself included) although they are rare and therefore the most expensive. See the Clarity grading system in the image at the bottom. COLOUR Here’s a fun fact for you, Diamonds come naturally in every colour under the sun however most of us desire those perfectly colourless stones. Colour is usually graded from D –Z, where D is absolutely colourless, and each grade below is slightly more intense in hue. Many of these colour distinctions are so subtle that they are invisible to the untrained eye but these differences make a huge impact in Diamond quality and price. Fancy coloured Diamonds go beyond this scale, as they are valued in their own right. We have a beautiful natural yellow Diamond Ring available from our latest Festive Collection. CARAT The weight of a Diamond is traditionally measured in carats, where one carat is equivalent to 0.2 grams. The higher the carat weight, the larger the stone is and therefore the higher the price. Price doesn’t go up proportionally with the carat weight though, as the larger a stone is, the harder it is to find, and the rarer it becomes. Remember, all of the four C’s can’t be considered alone when grading a Diamond, for two Diamonds that are of equal carat weight for example can be of completely different value due to the colour, cut and clarity differences! So there you have it, a useful tool for when you’re looking for that perfect Diamond. If you need more expert advice...you know where to find us! Explore our Diamond jewellery collections .
