There are many aspects to consider when choosing the perfect diamond for you or your partner. Without question, the most important consideration is personal preference. The reason behind what may attract someone to any given diamond ring is rarely questioned. It either catches your eye or it doesn’t! and individual taste is the one thing that remains pure, having no suggested guidelines or rules.

However, it is certainly worth taking into account some specific aspects when selecting the perfect diamond.These are known as the 4 C’s.


This determines how much a diamond will sparkle. A quality cut grade brings out the full potential of diamonds natural sparkle. The cut is responsible for the quality of a diamond’s proportions and symmetry, allowing it to capture and reflect the light. If a diamonds Pavilion is too deep, the centre would be noticeably darker.

The most popular top selling diamond cut shape is known as the ‘Round Brilliant’. Also highly desirable are the Princess and Emerald cut. Other available choices include Marquise, Pear, Heart, Oval, Radiant, Cushion and Asscher.

Interestingly the cut of a diamond is considered the most important factor for reasons such as, two possible diamonds can be equal in carat weight, yet the colour and clarity can differ in appearance and value simply because of the differences in cut quality. It is also considered the most complicated of the 4 C’s, due to the fact carat weight, colour, clarity values and rarity are linked to the diamonds natural formation. The cut quality is the result of human decision and a diamond cutters skills alone!!


Is the measure of tiny imperfections found in any diamond. It is rare to find a flawless diamond and would result in a much higher value. These imperfections are known as ‘Inclusions’, mainly occurring during the diamond crystallisation period before discovery or damage from the mining process. This can range from dark dots, minute white points, cracks or scratches. The fewer the ‘inclusions’ the more valuable the stone.

We all know the word carat when it comes to jewellery. Carat weight is simply a measure of a diamond’s weight.1 Carat is equal to 200 Milligrammes. Carat refers to the diamond weight only, not the actual size. Some diamonds are cut to maximise carat weight though this will inevitably reduce its sparkle. It is recommended that for the ultimate diamond, a balance of quality and cut is important.



Finally, the remaining of the 4 C’s to consider is ‘Colour’. The more absence of colour, the rarer the stone is likely to be, increasing its value. The colour created in diamonds is caused when the crystal grows in the earth. Possible traces of nitrogen and pressure involved in the formation of a diamond creates distortion in its structure and can also be a contributing factor in the presence of colour. The colour is measured on a letter scale ranging from D – Z, d being the most colourless down to z having the most colour.

Choosing the correct diamond can be a daunting prospect, due to the vast choice we are presented with today, not only that, the sheer amount of information on the diamond selection available can be overwhelming! However, it can be easy to forget that there are different types of value and that the value of a diamond is not necessarily in the rarity or cost, but in the sentiment that any diamond ring represents. Choose the diamond ring that will bring out the sparkle in you! as opposed to the sparkle of the stone, whether that be the rarest, most valuable diamond you can find or a diamond as real and as flawed with imperfections as any humans !!

All diamonds hold a uniqueness all of their own, no two would ever be the same, and that, right there, is the beauty of any diamond!
