The value of a diamond is determined by its quality and individual characteristics. Naturally you will want the best quality diamond you can afford.
Before you buy a diamond, it is best to have an understanding of what you are buying so that you are able to make an informed decision.
Learn about cut, clarity colour and carat weight. These qualities are what defines a diamond and are known as the 4 C’s. Obtaining some knowledge and an understanding about the 4 C’s is an important first step towards buying the right diamond.
To learn more about diamonds please read through the short overview of information.
The cut of a Diamond is the only property which is totally dependent on man.
Cut refers to the shape, proportions, symmetry, and finish or make of the diamond. A Diamond’s cut will influence the brilliance and fire of the diamond, and is what gives a diamond its beauty.
Did you know that if a diamond is poorly cut, the colour and clarity can not make up for it? Diamond Cut is therefore one of the most important aspects to consider when choosing your diamond.
Diamonds are found in a variety of colours.
The rarest diamonds are ones that have a colourless grading or diamonds with fancy colours such as greens, blues, reds and pinks. The colour of a diamond has a significant impact on its value. The diamond colour scale ranges from D to Z, D being colourless down to Z which is light yellow. Even though the most valuable diamond is a D colour, a diamond which grades G colour through to J colour will appear nearly colourless.
Diamond clarity refers to the presence of identifying characteristics on and within the diamond.
Most diamonds contain what are called inclusions; these have been caused by the constantly changing conditions during the different phases of the diamond’s creation. Diamonds are graded for clarity under 10 power loupe magnification. Clarity-grades range from Internally Flawless (IF) to Pique 3 (P1 or I1).
While Flawless diamonds are the rarest, a diamond does not have to be flawless to be beautiful.
The weight of a diamond is expressed in carats.
This is the weight of measure that jewellers will use to weigh diamonds. One carat is divided into 100 points. A diamond weighing one quarter of a carat can also be described as weighing 25 points or 0.25 carats. Carat is often confused with the size of a diamond, even though it is actually a measure of weight or a diamond’s mass. The size of a diamond is measured in millimetres. Larger diamonds are found in nature with much less frequency which makes them more valuable.
A certified diamond is a diamond that has been graded, tested and examined by a team of independent fully trained gemologists who then issue a Diamond certificate for that diamond.
Independent certification is essential. It provides an accurate, unbiased description of the quality of the diamond, and assures you that the diamond is natural and untreated. When shopping for loose diamonds it is extremely important that they are certified.
Fluorescence is the visible light some diamonds emit when they are exposed to invisible ultraviolet rays (UV), which is an essential component of daylight.
It can have an impact on the appearance of the diamond, which can result in the diamond appearing blue, or in rare instances the colour may appear to be yellow, white or have a hazy/oily look.
