4 Cs

Diamonds are valued on four key dimensions and they are all important when selecting the perfect stone. At Kamstones, we ensure that all the diamonds we source meet a specific standard along these specifications. A small change in a diamond grade can lead to huge price changes, so we keep this in mind and always look for the sweet spot for our clients. Lastly, to ensure consistency, we only use diamonds graded by GIA, the most reputable and consistent gemology institution in the world. To learn more about these characteristics and our philosophy regarding them, keep reading.

Definition: Carat refers to the weight of the diamond, 1 carat is equal to 200 milligrams. However, in the jewelry industry, you might also hear carats referred to as points (1 carat = 100 points). For example, 0.50 carat ring is called a 50 pointer.

Our Philosophy: Carat weight is not always synonymous to the size of the diamond because diamond shapes 'carry' their weight differently. For example, an oval diamond spreads its weight around well but a cushion diamond doesn't. At Kamstones, we place a lot of focus on not just the carat weight but the dimensions of the stone to ensure you get the largest diamond within your budget.


Definition: Clarity refers to the absence of inclusions or blemishes in a diamond. An inclusion occurs when small crystals are trapped in a diamond during formation. The number, size, nature and position of these irregularities determine the clarity grade. The image above shows the grade spectrum used to assess all diamonds. 

Our Philosophy: Most inclusions are too tiny to be seen with the naked eye; however they are visible to a professional diamond grader under magnification. At Kamstones, we ensure our clients' diamonds are 'eye-clean', which means we only select stones that do not have visible imperfections.


Definition: Color refers to the absence of color in a diamond. The degree of colorlessness ranges from D-Z (see image above). The presence of color in a diamond is sometimes referred to as warmth.

Our Philosophy: Up to a certain grade level, the difference in color grades are not detectable by an untrained eye. This 'sweet spot' varies across diamond shapes because some shapes show color more than others. For example, an emerald J color stone is going to show more yellow than a cushion J color stone. At Kamstones, we have mastered the 'sweet spot' down to a science for each stone and will give you this guidance as you narrow down your top stone selections.


Definition: Cut refers to how well a diamond's cut allows it to interact with light. A well cut diamond will have proportions and symmetry that allow it to sparkle under light. The grading scale categorizes cut as excellent, very good, good, fair or poor.

Our Philosophy: At Kamstones, we only source diamonds with very good or excellent cuts and this is why our diamonds always sparkle magnificently.
