Diamond Cut
Not to be mistaken with shape, your diamond cut is an important characteristic to consider when purchasing a diamond. The cut will ultimately govern how well the light is refracted; giving the diamond it's sparkle.
What Is Diamond Cut?
Cut is determined by symmetry, proportion and polish. More than any other factor, cut determines the beauty of the stone. Tiffany diamonds, from the smallest to the largest stone, are always cut to prioritise brilliance over carat weight.
Diamond cut is often interchanged with diamond shape; however, they refer to different things. The most important of the 4Cs, cut refers to how a diamond's facets interact with light, whereas diamond shape refers to the geometric appearance of a diamond.
Why Is Diamond Cut Important?
Diamond cut is what determines how much a diamond sparkles. Even a stone with excellent colour and clarity can appear lifeless if it is poorly cut. When a diamond is cut correctly, light enters the stone, reflects internally, and returns to the eye with exceptional brightness, fire, and brilliance.
At Jabour & Co, cut is never compromised. Every diamond we select is carefully assessed for balance, symmetry, and light performance, ensuring it delivers maximum brilliance for its size. Our approach focuses on craftsmanship and precision rather than chasing numbers on a certificate.
This attention to cut is what separates an ordinary diamond from one that truly comes alive and ensures your ring remains as captivating decades from now as it is on the day it's given.
Jabour & Co Diamonds
While many jewellers accept a wide range of cut grades, Jabour & Co applies a far more selective standard. We do not rely solely on labels each diamond is assessed individually for its proportions, symmetry, and overall light performance before it is approved for our collections.
Diamonds that are cut too deep or too shallow allow light to escape through the sides or base of the stone, reducing brilliance and sparkle. Likewise, poorly aligned facets disrupt the flow of light, resulting in a diamond that appears dull or lifeless, regardless of its other grades.
At Jabour & Co, only diamonds that demonstrate exceptional balance and optical performance are selected for our engagement and bridal pieces. Our gemmological standards apply to individually chosen diamonds, carefully matched to specific designs to ensure each ring performs beautifully in real life not just on paper.
Diamond Cut Chart
Every diamond is graded on its cut quality and is given a grade, ranging from excellent to poor. The higher the cut grade, the better the fire and shine that is emitted from the diamond. Take a look at our diamond cut chart to understand each grade.
IDEAL
Excellent & Very Good Cuts
A diamond with proportions optimized for maximum light performance. Light rays enter the top of the diamond, reflect internally off the pavilion facets at precise angles, and are efficiently refracted back out through the top towards the viewer. This demonstrates excellent light return, which translates to high brilliance, fire, and scintillation.
SHALLOW
Good Cuts
A diamond with a shallow pavilion. Light rays enter the top, but many escape through the sides of the pavilion, particularly from the bottom-side facets, rather than reflecting back to the viewer. This indicates moderate light return, with some sparkle but less concentrated brilliance than an ideal cut.
DEEP
Fair Cuts
A diamond with a noticeably deep pavilion. Light rays enter the top of the diamond, but instead of reflecting back up through the top, many escape through the bottom and lower sides of the pavilion. This illustrates that a deep cut allows light to leak out, resulting in poor light return and reduced sparkle.
