Diamond shapes Ensuring you understand the fundamentals of diamond quality will not only help you determine whether your diamond is the quality you desire - but also that you’re not paying more than you should be. To the untrained eye, it’s often near to impossible to tell the difference between two closely graded diamonds - however it can make a vast difference to the price.

The 4 Cs: Cut, Colour, Clarity, and Carat

Firstly, it’s imperative to recognise the importance of the 4Cs. These are the main 4 qualities that determine the worth and rarity of your diamond.


Firstly, we’ll take a look at the ‘cut’ of the diamond. This can have a vast effect on the price and quality of your diamond, so you need to pick carefully.  The Gemological Institute of America (GIA) grades the cut of diamonds as Excellent, Very Good, Good, Fair, and Poor. This grading system refers to the pattern cut into the gemstone, which shows off the bright and dark areas of the diamond. At Diamond Boutique, we only offer ‘excellent’ and ‘very good’ diamonds, so you know your stone is of the best quality it can be.


Colour also changes the price and quality of a diamond, to varying degrees. Most diamonds are white, and graded on a scale according to their purity. However, some offer hints of blues and yellows throughout, thus changing the grade of the Diamond. An abnormal fluorescence can change the way your diamond might look under UV light, and may not always be a good thing. Alternatively, these unusual stones might be just what you are looking for! The traditional diamond scale runs from D - Z, and much of our work is done within this scale. Colours that move above Z are considered to be some of the rarest and most expensive diamonds in the world, showcasing colours not seen in almost any other diamonds.


The ‘clarity’ of the diamond is yet another imperative quality indicator. The clarity rating of a diamond refers to the number of inclusions (visible impurities in the inside of the gemstone) or blemishes (spots on the diamond’s surface) that affect the diamond’s ability to refract light. Just as the colour of your diamond is based on a scale, the clarity can also be graded for your ease. This scale runs from FL to I2, and outlines the diamonds with the highest quality clarity. At Diamond Boutique, we offer diamonds above the SI1 category, all of which show off a clarity that is sure to make your new ring truly sparkle.


The ‘carat’ is usually the one people think about first when you consider the quality of a diamond. Contrary to popular belief, the carat doesn’t actually refer to the size of a diamond - but the weight. Of course, the higher the weight - and thus the higher ‘carat’ - the more expensive the diamond will be. If you’d like to browse our collection of gorgeous diamond rings, take a look at our website.
