A diamond’s value, rarity and beauty are determined by factors that are known as the Four Cs – Cut, Colour, Clarity and Carat. All Four C’s represent the main components that determine a diamond’s beauty and structure. Know the Four Cs and know your diamonds!
A diamond’s cut is the most important characteristic to consider when buying a diamond because it determines its brilliance and sparkle. It is all about perfect symmetry and alignment of its tiny, mirror like facets that will beautifully reflect light and maximize brilliance.
While the diamond’s sparkle catches the eye first, its colour is the second aspect to consider when choosing a diamond. What you are looking for in the diamond is what’s not there as the highest quality diamonds are colourless, while those of lower quality have noticeable colour. The subtle differences are graded on a colour scheme from D (colourless) to Z (light yellow or brown).
Diamond clarity is the assessment of small imperfections, or inclusions, on the surface and internally. Because diamond are created by tremendous pressure and heat deep within the earth, virtually all diamonds will contain microscopic inclusions and blemishes which are invisible to an unaided eye and do not affect a diamond’s beauty in any way. Diamonds with fewer imperfections are deemed to have a higher clarity grading, ranging from Flawless, or FL, to I, signalling a number of inclusions.
Carat is the measure for a diamond’s weight, not necessarily its size. A carat metric measure is defined as 200 milligrams (or one carat) and precise measurements are taken to the hundredth decimal place to ensure complete accuracy. As the carat weight of a diamond increases so does its rarity and therefore its price. It is important to know that two diamonds can be of an equal carat-weight, but their value can differ greatly due to their cut, colour and clarity.
