Understanding the Secrets Cut

Secrets Shhh

Whether you’re a jewellery newbie, or you’ve been in the game for a while, there’s no doubt that you’ve heard the term “4 C’s” before. Each ‘C’ plays a crucial role in the overall appearance of your stone, however the ‘cut’ of a stone is the most important aspect to consider.


GIA (Gemological Institute of America) is one of the worlds most recognised and greatly respected diamond laboratories. This organisation was developed to give guidance and standardise the diamond industry. They are most famous for creating “4 C’s” – the globally used matrix to determine the worth and quality of a stone. The 4 C’s are Colour, Cut, Carat and Clarity.

Similar to how a stone’s colour is graded, the cut is graded from poor to excellent. The proportions of a diamond refer to the relationship between the table size, crown angel and pavilion depth and how light refracts from these areas.

It is extremely important to understand the significance of a stone’s cut, as, if it is not cut to the correct proportions, design or weight the whole appearance is directly affected, and in turn dulling the stone’s natural beauty and shine. Poorly cut stones will affect three major aspects of the stone’s appearance- Brilliance (brightness from maximum light refraction), Fire (how the light reflects the spectrum of colour) and scintillation (the movement of light and dark flashes, aka the sparkle).

With a stone cut too low, the light will travel from the top to the bottom and if cut too deep the light will travel to the side. The ideal cut will guide the light back through the top of the stone, creating the ultimate sparkle.
