Hold an Aukera round brilliant diamond under a specialised viewer and something quite magical happens. Eight hearts appear on one side. Flip it, and eight arrows appear on the other. The pattern isn't printed onto the diamond or added afterwards. It forms entirely from the way the facets are cut and aligned, and it only appears when that cutting reaches a particular level of precision.
This is what a Hearts and Arrows diamond is. Let’s understand what creates the pattern, what it means for light performance and why it’s the ultimate expression of rare love.

Key Takeaways
- A pattern on a Hearts and Arrows diamond is a result of cutting precision and optical symmetry
- A certificate saying Excellent Cut does not confirm a Hearts and Arrows pattern
- The premium reflects cutting craftsmanship and precision
- Lab grown diamonds are best suited to achieve Hearts & Arrows optical symmetry.
- Aukera's Enhanced Hearts & Arrows™ reveals twelve hearts and twelve arrows instead of the traditional eight, independently verified by IGI and GemEx
How Does the Hearts and Arrows Pattern Form?
The pattern is purely optical and is a result of how the diamond's facets are positioned relative to each other. Nothing is engraved, etched or applied.
Precision Faceting and Optical Symmetry
A round brilliant has 58 facets. These facets are cut to proportions. In a Hearts and Arrows cut diamond, every facet is aligned to a significantly higher degree of precision than that.
That alignment creates optical symmetry. Light moving through the diamond reflects in a consistent, symmetrical pattern rather than a variable one. The Hearts and Arrows pattern is what that symmetry looks like under a specialised viewer. It either appears clearly. No ambiguity, no interpretation required.
Optical symmetry dictates how light performs inside the diamond. It contributes to strong brilliance, fire and scintillation. It’s important to note that it does not really guarantee superior performance in every stone. Colour, clarity and carat play their part too.
Why Only Round Brilliant Diamonds Display the Pattern
The Hearts and Arrows diamond is a pattern unique to round brilliant cuts. Due to the different facet structures of ovals, cushions and emerald cuts, the same pattern doesn't appear.
Most round brilliants don't have Hearts & Arrows either. The pattern needs a level of cutting precision that goes well beyond a standard round brilliant, even a well-cut one.
How Does It Compare to an Ideal Cut Diamond?
Ideal Cut is a grade. It describes how well a diamond's proportions and faceting meet a particular standard. A diamond can score Excellent or Ideal on cut without showing any Hearts & Arrows pattern at all.
Hearts & Arrows is about optical symmetry. Facet alignment at a specific, higher level of precision. A Hearts and Arrows cut diamond can be Ideal Cut, but one doesn't imply the other. Excellent Cut on a certificate is a starting point, not a confirmation that the pattern exists.
| Excellent Cut | Ideal Cut | Hearts & Arrows | |
|---|---|---|---|
| What it describes | Cut quality | Cut quality | Optical pattern and symmetry |
| Requires round brilliant | No | Depends on grading system | Traditional H&A pattern: yes |
| Visible H&A pattern? | Not necessarily | Not necessarily | Yes, when properly achieved |
| Focus | Proportions | Proportions and cut | Facet alignment and optical symmetry |
Benefits of Choosing a Hearts and Arrows Diamond
Superior Craftsmanship
Achieving the pattern requires cutting to tolerances that go considerably beyond standard grading requirements. Each facet has to land precisely. It takes longer, loses more rough diamond material and produces fewer finished diamonds per rough than a standard cut. The craftsmanship is part of what you're paying for, separate from the light performance question.
Exceptional Brilliance and Fire
Brilliance is the white light that comes back upward through the crown. Fire is a spectral colour in flashes. Scintillation is what happens when the diamond moves.
In a well-cut hearts and arrows diamond, precisely aligned facets create more consistent and predictable light return than facets with less alignment. That can translate to stronger brilliance, fire and scintillation than a standard round brilliant at similar grades. The specific diamond always matters more than the general principle.
Consistent Light Performance
Most diamonds look good in a jewellery store. The interesting question is how they look everywhere else. Precisely aligned facets mean light moves through the diamond consistently, not just under showroom conditions. The same diamond that catches attention at dinner tends to keep doing it on an ordinary Wednesday morning.
Is This Diamond Cut Worth It?
Absolutely.
Hearts and Arrows diamonds are more premium primarily because of the high standard of precision, cutting skill and time as well as the material loss in the process. If optical symmetry and measurable craftsmanship matter to you, that premium makes sense. If your priority is carat size or a particular colour grade, the same budget might produce a different balance elsewhere.
The pattern itself isn't visible without a specialised viewer. Most people looking at the ring day to day aren't seeing Hearts and Arrows. What they're experiencing is the light performance that the precision behind the pattern produces.
Lab Grown Hearts and Arrows Diamonds
The pattern comes from cutting, full stop. The optical symmetry of Hearts & Arrows has nothing to do with the origin of the diamond.
For all intents and purposes, a lab grown Hearts & Arrows diamond has the same pattern as a mined diamond cut to the same specifications. The cut determines everything.
Aukera's Enhanced Hearts & Arrows™ is a lab grown Hearts and Arrows diamond cut to a twelve-heart, twelve-arrow standard rather than the traditional eight, the result of a proprietary cutting approach that requires a higher level of precision. Only around 1 in 10,000 diamonds have the consistency needed for a standard Hearts & Arrows pattern. The Enhanced version demands more.
Every Enhanced Hearts & Arrows™ diamond comes with an independent IGI Enhanced Diamond Certification that can be easily verified on the IGI website using the report number. Every diamond also receives a GemEx 3VH score. GemEx measures brilliance, fire and scintillation independently. 3VH means all three are at their maximum at the same time.
For anyone buying lab grown diamond jewellery, the same cutting standards and verification methods apply as with any other diamond. Origin changes nothing about what the cut can achieve.
How to Verify the Pattern Before You Buy
Check the Diamond Certificate
A standard grading report covers cut, colour, clarity and carat. For a Hearts and Arrows diamond, cut grade is a starting point. Excellent or Ideal cut is necessary but doesn't confirm the pattern exists. The certificate and the optical imagery serve different purposes and both matter.
For Aukera's Enhanced Hearts & Arrows™, the IGI Enhanced certificate specifically confirms the enhanced designation. The report number is verifiable on the IGI website by anyone, at any time. Aukera Enhanced Hearts and Arrows also comes with an additional certificate - GEMEX - that certifies for light performance
Ask for Hearts & Arrows or Optical Images
Ask to see the viewer images. The hearts should be on one side, and arrows on the other side. You should get a clear, well-defined and symmetrical image. A vague or partial pattern is worth questioning before paying a premium for it. For the Enhanced Hearts & Arrows™, the twelve-heart, twelve-arrow pattern is what distinguishes it from the standard version. One should consider the certificate and image before choosing.
Tips for Choosing the Right Diamond
Cut first, always. Carat is the most visible number and the one that matters least to how a diamond actually looks in real conditions.
Look at proportions. Depth percentage, table percentage and crown angle all affect how light moves through the diamond. A Hearts & Arrows diamond should have these within a controlled range.
Choose colour for the setting. Yellow gold suits warmer colour grades. White gold and platinum suit colourless grades. The right colour grade depends on the metal rather than the highest available grade.
Check clarity for eye-cleanliness rather than certificate grade alone. VS2 is typically eye-clean in most cuts.
Ask for Hearts & Arrows imagery specifically if you're paying a premium for the pattern. A verbal confirmation is not the same as seeing the actual viewer image.
See the diamond in person where possible. Diamond rings at Aukera are available to view at the Diamond Bar in store, where light performance is visible rather than described.
For lab grown diamond pendants,lab grown diamond necklaces and lab grown diamond mangalsutra, the cut and optical symmetry matter just like in a ring format.
Buy from a jeweller who can show you the certification, the imagery and the verification. Aukera's Enhanced Hearts & Arrows™ comes with IGI Enhanced Certification and a GemEx 3VH score, both independently issued and publicly verifiable.
