When beginners buy sapphires, they often repeat the same sapphire cut mistake. They focus only on size or color while ignoring the cut. Yet, the cut is the soul of the stone because it controls brilliance.
A poor cut causes two common problems:
- Windows – light leaks out through see-through areas.
- Extinction – light gets trapped, creating dark patches.
Both issues make a sapphire look dull. Even a 5-carat stone loses life if the cut is wrong. By contrast, a smaller sapphire with ideal proportions shines brighter and carries more value.
“Brilliance depends on cut, not carat weight.”
Why Cut Defines Value
Case Study: Two Stones, Same Weight
For example, dealers compared two sapphires of equal weight.
- The first stone had a shallow cut, so it lost 40% of light through a window.
- The second stone had balanced proportions, therefore it returned almost 90% of light.
As a result, the well-cut gem sold faster and at a higher price. Buyers recognized the sparkle instantly.
What Buyers Prefer
Research confirms this. Surveys show that 62% of sapphire buyers prefer brilliance over carat weight. Because of this, cut remains the top factor driving real market value.
Expert Advice on Avoiding Mistakes
With over 40 years in the gemstone trade, I have seen many collectors regret their sapphire cut mistake. Once jewelers set a poorly cut stone, flaws in brilliance stand out clearly.
Don’t rely only on carat or color. Instead, always check how the stone reflects light before you pay for it.

FAQ: Sapphire Cut Mistakes
What is the biggest sapphire cut mistake?
Many buyers focus only on size or color. Because they ignore cut, even rare stones lose their brilliance.
What does a sapphire window mean?
A shallow cut creates a window where light leaks through. As a result, the stone appears flat and lifeless.
Can extinction be avoided?
Yes. A deep cut causes extinction, but if you choose proper angles, you can reduce the dark areas.
Can a poor cut be fixed?
A skilled cutter can improve brilliance. However, recutting reduces weight and increases cost, so weigh options carefully.
