A diamond cut is a process of taking a rough diamond crystal formed over a thousand years under pressure and heat. Then turning it, for example, into an oval or square cut with a typically desired result of exposing its maximum brilliance, fire, scintillation appearance, and shape.
How these factors like brilliance, polish, and facet surface affect the cut, shape, and grading of a diamond is paramount in fully understanding what creates the stunning and high value of this precious gemstone.
Diamond Cut Explained
There is a physical, chemical, and optical process going on when a diamond is cut. It’s a delicate process undertaken by experienced master cutters after years of training with the goal to create, enhance, or preserve the three plus one following attributes:
|Diamond Cut Attributes||Goal|
|Brilliance||Amount of brightness reflected from the external and internal parts of a diamond back to a human eye viewer|
|Fire||Rainbow flash colors visible amount throughout all diamond’s angles|
|Scintillation||Dark to bright shades of light reflected when diamond or person moves|
|Pattern*||e.g., 57-58 facets of a modern round cut|

Here are the diamond cuts a master cutter usually considers before cutting. This is while keeping the attributes of stone brilliance, flash-light fire, and scintillation moves (dark to light or vice versa) to create the ideal diamond shape by applying the suitable cut and polish.
On the other hand, we have precious gemstones types characterizations that focus on clarity instead of solely shape or brilliance, like concerning this guide I created on VVS diamond explained.
So know exactly does a diamond cut affect the end product and consumer?
Round Brilliant Cut Explored
No doubt, according to statistics, the brilliant round cut is by far the most popular, but why?
Benefits of Round Brilliant Cut Diamond

- Most offered by jewelry traders therefore availability at different carats high
- Maximum symmetry (constant proportions) with as many facets as possible
- The easiest cut to sell and pawn later on
- This circle cut diamond gemstone easier to grade than other cuts
The last bullet point means that, unlike other diamond cuts, the round brilliant has been, after years of research, graded by the Gemological Institute of America (GIA) into five areas of reference.
GIA’s Cut Scale
As you can see, grading a diamond’s cut is a complex process taking many factors from crown height, depth to bottom size culet, and the opposite star facet atop, including the different facets and diameters and so forth.
Work that is undertaken by master cutters and graders using their experience and modern computer-aided technology (CAD) to best estimate the cut quality of diamonds.
Diamond Cut Scale Exp
|Excellent||Best cut regarding flawless brilliance, fire, scintillation, and patterns|
|Very Good||Brightness, fire, and dark/light reflections nearly as good as excellent|
|Good||Though external light is still good, internal light, rainbow colors, internal reflection are satisfactory|
|Fair||External and internal light entrance and exit from the diamond not as good|
|Poor||Light leakage after entrance prevent leaving little reflection of brilliance, fire, scintillation|
