Know Your Diamonds: The 4 C’s


Funnily enough, when speaking of colour in regards to diamond quality, it is actually the lack of colour that determines quality.

Most of the time, the closer a diamond is to being completely colourless, the more valuable it is.



Commonly mistaken as the shape of a diamond, in this case, cut actually refers to the how well a diamond’s facets interact with light.

This is a little confusing considering that the diamond industry uses ‘cut’ both ways. One refers to the shape, like Emerald Cut or Princess Cut, and the second usage refers to the reflectiveness quality described above.





Different from a Karat, which refers to the quality of gold, a carat or the carat weight refers to the size or mass of any diamond. Each carat is equal to 200 milligrams or 0.2 of a gram.

In order to determine the exact size of a diamond, a point scale was introduced. Here, a point is equal to 1/100th of a carat. This allows for an exact measurement of a diamond up to the hundredth decimal point.

You may have heard the term used like this: a 50-point diamond, which refers to a 1/2 carat diamond.

In the instance of carat weight, bigger does not necessarily mean better.


Diamond carat size not to scale.


Since diamonds are unique in their nature, they also tend to have their own individual set of flaws. These flaws or ‘inclusions’ can be a variety of things including air bubbles, cracks, or other minerals all trapped within the diamond itself.

Each and every diamond is examined at a 10x magnification, and naturally, the fewer flaws or inclusions there are, the more valuable it is.
