Every diamond tells a story. Like a silent whisper from the past, its cut captures centuries of art, elegance, and passion. Whether you’re cherishing a moment or making a bold statement, the diamond cut you choose speaks volumes about your feelings and style.

A diamond’s brilliance, determined by its cut, reflects its ability to capture light. A well-cut diamond will capture and reflect light, seemingly glowing from within and giving off an entrancing sparkle. A poorly cut diamond might appear dull or lackluster, regardless of its other qualities.

At Keezing Kreations take pride in crafting countless breathtaking diamond cut designs. We share our knowledge of the most popular diamond cuts, the most special ones for engagement, what makes each diamond cut unique, why cut/shape matters, and how to choose a diamond cut.

Cut vs. Shape: What’s the Difference?

Though used interchangeably, ‘cut’ and ‘shape’ have distinct meanings in the diamond world. Understanding the difference is important for both sellers and buyers.


  • Refers to the appearance or overall silhouette of the diamond.
  • It’s the first thing most people notice and is often the primary factor when choosing a diamond for aesthetic reasons.
  • Shapes can range from round to square, oval to marquise, and many others in between.
  • Each shape has unique characteristics and appeals to different tastes.


  • Refers to how well the diamond has been crafted from its rough form, influencing its overall brilliance.
  • It includes factors like symmetry, proportion, and polish.
  • The quality of the cut plays a role in determining the diamond’s overall beauty and value.

The shape appeals to our aesthetics and emotions, while the cut determines how brilliantly a diamond will shine.
