Learn More About The 4cs

The key to finding the right diamond piece that captures your love is to make the perfect balance between what gemmologists refer to as the 4Cs. These are four headings, used by the GIA (Gemmological Institute of America), who are often seen as the authority on diamonds and gemstones, and they refer to Colour, Clarity, Cut and Carat. It is all about striking a perfect balance between those things to find the right diamond piece for you.

It is a myth that diamonds come out white – infact the whitest diamonds are actually the rarest of them all. The colour scale used to indicate this colour tint is measured runs from D To Z. At Ernest Jones we grade all diamonds against the accurate GIA scale to measure the degree of colour included. The GIA scale runs from D, representing the purest, colourless stones and continues to Z, the most tinted stones.


As natural minerals, diamonds bear nature’s mark through what are referred to as inclusions. Most diamonds feature inclusions, with entirely flawless diamonds being exceedingly rare. The clarity of a diamond is determined by closely examining the stone under ten times magnification and mostly cannot be seen by the naked eye. Diamonds with higher clarity grades are deemed more valuable, and increasing the weight of the diamond also increases the likelihood that more inclusions would be present, thus making more weightier diamonds much more expensive to maintain consistency in clarity grades.

Cut is the only aspect that is determined by skill and craftsmanship by individual jewellers, as diamond cutters often have to work from a larger raw stone that must be cut into the desired form. The cut of the diamond often influences how the light performs in diamonds as well; if the cut reaches near perfect proportions the light will reflect within the diamond much better. All our diamonds are expertly cut with fine symmetry, geometric precision and exact angles to form perfectly proportioned facets, allowing for a beautiful diamond which intensely glistens in the light.

One of the most popular misconceptions is that Carat refers to the size of the diamonds. But carat measurement actually refers to the weight of diamonds. In styles where lots of smaller diamonds are used, then the carat weight refers to the total weight of all the diamonds combined. Carat is one of the most famous types of diamond measurements and are not to be confused with the carat of the gold material type. The higher the carat, the heavier the diamond will be, which may result in a bigger diamond but also something that feels a lot weighted on the finger.
