The 4Cs Of Diamonds
The most important of the 4Cs is cut because it has the greatest influence on a diamond's sparkle.
Have you ever noticed how many surfaces a diamond has? A diamond's cut refers to how well-proportioned the dimensions of a diamond are, and how these surfaces, or facets, are positioned to create sparkle and brilliance. For example, what is the ratio of the diamond's diameter in comparision to its depth? These small, yet essential, factors determine the diamond's beauty and price.
Of the 4Cs (cut, colour, clarity, carat), cut has the greatest influence on a diamond's beauty and sparkle.
The second most important of the 4Cs is colour, which refers to a diamond's lack of colour. The less the colour, the higher the grade.
Did you know that it's very rare to find a diamond that doesn't have any colour at all? In fact, diamonds are found in almost any naturally occurring colour, including grey, white, yellow, green brown, and pink.
Diamond colours range from D (Colourless) to K (Faintly Coloured).
Often the least important of the 4Cs because the tiny imperfections are often microscopic.
Diamond clarity is the assessment of small imperfections on the surface and within the stone. Surface flaws are called blemishes, while internal defects are known as inclusions. In most cases, a diamond's beauty is not affected by these in any way since most inclusions can't be seen with the naked eye. When referring to inclusions, gemmologists often use the term "internal characteristics" instead of flaws. Internal characteristics are what give a natural diamond its character. It's also important to note that diamonds with the fewest and smallest inclusions receive the highest clarity grades - and the higher price tags to reflect that.
Remember, all diamonds are unique, not perfect. They are mad underground through enormous pressure and heat. Natural inclusions and blemishes are inevitable.
The term carat actually refers to the diamond's total weight and not its size.
The term carat is often misunderstood. It refers to a diamond's weight, not its size. Another misconception is that a larger carat weight is always better than a smaller carat weight. While it's true that a big rock can be a status symbol, carat weight is not related to sparkle. Beautiful sparkle is the result of a well-crafted cut. In fact, a high carat weight diamond with a poor cut look smaller than a diamond with a smaller carat weight and a very good cut.
