The value of a diamond is determined by its quality and individual characteristics. Before you purchase a diamond, it is best to have an understanding of what you are buying so that you are able to make an informed decision. Top Image Jewellery encourages you to learn about cut, clarity, colour and carat weight. These qualities are what defines a diamond and are known as the 4C’s. Obtaining some knowledge and an understanding about the 4C’s is an important first step towards buying the right diamond for you
The cut of a diamond is the only property which is totally dependent on man and refers to the shape, proportions, symmetry, and finish – or make of a diamond. Cut will influence the brilliance and fire of a diamond and is what gives it beauty. Did you know that if a diamond is poorly cut, the colour and clarity cannot 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 have a colourless grading or green, blue, red or pink colourisation. The colour of a diamond has a significant impact on its value. The diamond colour scale ranges from D to Z; D being colourless and Z being 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, which are 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 measure that jewellers 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 one that has been graded, tested and examined by a team of independent fully trained gemmologists who then issue a certificate for that diamond.
Independent certification is essential. It provides an accurate, unbiased description of the quality of the diamond, and assures 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). 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.

The four most common precious metals used in jewellery creation are gold, silver, palladium and platinum. 9ct, 14ct, 18ct and 24ct gold is well-known for its dense, lustrous qualities, while silver has a white hue and is soft. Platinum is four times stronger than gold, while palladium is versatile making it ideal for both women’s and men’s jewellery.
Alternative metals such as the hypoallergenic cobalt, durable tungsten, silver-grey titanium and stainless-steel are also used widely in jewellery making today.
Precious metals can be finished in a variety of ways including high polish used for glamourous engagement rings, satin or matte finishes ideal for wedding bands, and brushed or hammered finishes which are popular for masculine rings.
