When buying a diamond it is important to do your research before you forfeit a large amount of your money. To make your journey enjoyable and hassle free we would like to offer consultations to assist you in the decision-making process. We ensure that you gain exceptional value. At the same time we strongly encourage consumers to do their own research and gain an understanding of what it is they are after. As such we have prepared this guide, wherein you will be taught the skills to ensure that you are purchasing a diamond according to your own standards.
How much should you spend on a diamond?
That is very much up to you. Some people consider one or two months’ salary a good guide for an engagement ring. The important thing to remember is that unlike a wedding dress, a diamond engagement ring is worn every day of your life so you would be wise to choose something that will continue to give pleasure year after year, because a diamond really is forever.
How do you determine the quality of a diamond?
To determine a diamond’s quality and worth you begin with the 4 C’s: Clarity, Cut, Colour and Carat weight. These are the traditional units of measure when looking at this precious stone, however, you must add one more imperative ‘C’ to the list and that is Certification.
The cut of a stone is not relating to the shape, but refers to the way the cutter has formed it to best ensure that light bounces within the stone and back out through the top. If it has a defective cut (too long or too short) the light refracts on the inside and falls out down the bottom. This decreases the brightness and lustre of the stone. A well cut stone is neither exceedingly long nor shallow, it is luminous and will always dazzle when dirty.
The grading system varies from Ideal Cut to Good and lastly, Poor Cut. With round diamonds, it is suggested to never purchase below ‘Very Good’ and ‘Good’ in all other shapes. Again, the better cut stone the more it will cost.
This relates to the marks of non-crystallised carbon called ‘inclusions’ found within the diamond. The inclusions vary in standards on the spectrum ranging from FL (flawless), SI1 to I3.
It is exceedingly rare for a diamond to be flawless (known as FL) and is the highest level on the spectrum. SI1 is in the middle of the spectrum and it is recommended when buying a diamond that you should not purchase lower than this standard. I3 is the lowest as it includes the most inclusions and is least clear.
The clarity grade is determined by several factors including:
- The size of inclusions.
- How many inclusions.
- The positioning of the inclusions - inclusions found under the table (top of the diamond) affects clarity grade more so than inclusions found under the side facets.
- The visibility of the inclusions – the more visible the inclusions to the naked eye the less favourable the grade will be.
