Buying a Diamond
Below is a simplified price indicator, based on the shape, colour, clarity and weight of a diamond. It gives an approximate price range where most diamonds within those criteria would fall. As mentioned, every diamond is different so it is possible to find, for example, two round diamonds of 1.00cteach with a G VS2 grading at different prices. Please contact us for specific options.

It is important to note that assessing a diamond is not an objective process, the colour and clarity grades are ranges that professional jewellers have been trained to judge and is a skill that is passed down generations. There are even different preferences for cut parameters and professionals, to date, still debate about what is the “best.” The individuality of the process is in fact what makes diamonds so unique and exciting!
With so many options available, it’s best to narrow down as many parameters as possible so that you will have a smaller selection to study and then make the final choice.
The 4 Cs
Cut refers to both the shape of the diamond and measuring how well the diamond has been cut so that it can reflect the most light, and thus achieve the most brilliance. Well cut diamonds also look bigger than poorly cut ones, even though they may weigh more!
The colour of a diamond is very important as it can affect the sparkle and, more so, the value quite significantly. Colour is measured on a scale starting from D (pure white) to Z but extends further to the fancy colour range. Diamonds at the extreme ends of the scale are the most rare and therefore the most valuable. Generally, diamonds graded I colour or better will look white to the naked eye.
Clarity refers to natural imperfections that are present in all but the rarest diamonds (referred to as flawless). The less inclusions, the better the clarity and professional jewellers can judge and grade the quality of a diamond based on the number, size, position and type of inclusion. Diamonds that are graded SI1 and above will generally have inclusions that cannot be seen with the naked eye.
The carat weight is perhaps one of the few characteristics of a diamond that is an exact science! This simply refers to the weight of a diamond, measured in carats (ct). In this regard, bigger is always better, but diamond prices increase exponentially with weight, so it is an important factor to consider.
