How do you know which diamond is right for you? Aside from just the basic determinants of a diamond's beauty and value, there are a plethora of other factors that go into making the ideal choice. The tools below will guide you towards making that perfect decision, and make you truly appreciate the intricacy that goes into cutting that perfect stone.


The anatomy of a diamond is summed up by 5 defining facets: Table, Crown, Girdle, Pavilion, and Culet. Scroll over the image below to see where these are located. When purchasing a diamond, these dimensions and the inter-related effects these facets have on each other will greatly affect pricing.

Measuring Diamond Carat Weight

The weight of a diamond, measured in carats, is often the popular determinant of its attractiveness amongst social circles. However, despite its prominence, weight is merely one aspect (and arguably not the most significant) that affects the value of a diamond. Use the slider below to get a pictorial understanding about weight.






Diamond Cut Grading

The cut of a diamond is a very important feature and sometimes overlooked. The right cut gives spectacular brilliance and conforms to the perfect geometrical balance for that stone. Look at some examples below that will help you identify the variances in cut quality.



Clarity Grading

The clarity of a diamond is of utmost importance. A raw diamond crystal is scrutinized by cutters to look for the perfect way to slice polished stones. Amongst the most important things that will be criticized during this analysis will be the level of inclusions, and how to avert them to amplify the flawlessness of each stone. There can be a wide arrangement of inclusions, and so to reduce this burden on the commercial world, the GIA has adopted a system to help identify the relative clarity of stones. Use the slider below to gain an in-depth understanding of how clarity is assessed.




Diamond Color Grading

The colour of a diamond is a defining aspect for its purpose. The rule of thumb is that more colourless a diamond is, the greater its value. Exceptions to this rule come from fancy and coloured diamonds that sometimes yield truly unique specimens. When deciding on a diamond colour itself, it is important to imagine how that diamond is intended to be used. If it is for a jewellery setting, whether it is gold or platinum will affect the appearance of the overall piece. For instance, a more coloured diamond on a gold setting may exhibit the qualities of a more colourless stone on its own due to how light is refracted through the facets and the surrounding jewellery. However, when we look at stones for their standalone value, within the colour grading spectrum, the more colourless the stone, the greater its value. Use the scale below to gain an understanding of the subtle differences between these shades.
