Hearts and Arrows Diamond Guide

Do not pay for the label, Hearts and Arrows diamonds need actual hearts images, arrows images, GIA data, video, and performance proof before they deserve a premium.
Most buyers think Hearts and Arrows is a certificate grade. It is not. It is a pattern claim, and I do not trust the claim until I see the actual hearts and arrows images.
I always start with GIA for natural diamonds. Not because the cut grade alone is enough, but because GIA gives me proportions I can actually trust. Softer lab reports do not give me the same confidence in those numbers.
Nice arrows in a face up photo are not enough. I want the hearts image too. If the seller cannot show the pattern, the buyer should not pay for the pattern.
What Hearts And Arrows Shows
The hearts image is viewed from the pavilion side. The arrows image is viewed face up. Together, they show optical symmetry in a round brilliant.
A true pattern should be balanced, clean, and consistent. Crooked hearts, split clefts, uneven arrows, or mismatched sizes weaken the claim.
What The Pattern Does Not Prove
Hearts and Arrows does not replace cut proportions. It does not prove the diamond is the right price. It does not make a bad color, risky inclusion, or poor value disappear.
For round brilliants, I still start with table 56 to 58 percent, depth 60 to 62.4 percent, crown angle 34 to 35 degrees, and pavilion angle 40.6 to 41 degrees.
| Evidence | What It Shows | What It Does Not Show |
|---|---|---|
| Hearts image | Pavilion side optical symmetry | Price value |
| Arrows image | Face up patterning | All light behavior |
| GIA report | Grading and proportions | True Hearts and Arrows proof |
| Video | Real movement | Exact pattern precision |
Common Pattern Problems
The most common issue is a near miss. The seller shows arrows, but not hearts. Or the pattern looks close enough to a beginner, but the hearts are uneven.
If the premium is real, the proof should be real.
- Uneven heart size.
- Split heart clefts.
- Twisted or short arrows.
- Uneven arrow shafts.
- Pattern images missing from the listing.
My Call On Pattern Claims
Do not pay a Hearts and Arrows premium without actual hearts and arrows images. A product label is not proof.
When the images are strong and the proportions are strong, Hearts and Arrows can be worth paying for if cut precision matters most to you.

Where Hearts And Arrows Earns Trust
Use Hearts and Arrows review only after the diamond already passes the normal round brilliant screen. A pattern image is not a replacement for cut proportions, price judgment, or inclusion review. It is extra proof when the buyer is paying for precision.
Mistakes I Would Skip
- Do not pay for Hearts and Arrows without actual hearts and arrows images.
- Do not confuse nice arrows with true optical symmetry.
- Do not ignore the GIA report because the pattern looks pretty.
- Do not let a retailer label replace proof.
Pattern Proof Example
A seller can show a round diamond with crisp arrows in the face up photo and call it Hearts and Arrows. That is not enough. I want the hearts image too. If the hearts are uneven, split, or twisted, the stone can still be attractive, but it should not be priced like a verified precision diamond. The buyer should pay for proof, not vocabulary.
Questions I Ask Before Paying For Pattern
- Can you provide the actual hearts image?
- Can you provide the actual arrows image?
- Are the hearts even, clean, and consistent?
- What premium am I paying for the Hearts and Arrows claim?
Where I Would Compare Pattern Proof
Use these sites as proof libraries, not automatic recommendations. I would compare performance evidence on Whiteflash and Brian Gavin Diamonds, then decide whether the actual diamond earns the premium. The proof matters more than the name.

Questions Buyers Ask Us
Think of a Hearts and Arrows diamond as a round brilliant with a precise optical pattern visible through special viewers. The hearts are seen from the pavilion side, and the arrows are seen face up.
No. GIA reports cut and proportion data, but Hearts and Arrows must be verified with separate images.
No. Some are strong, and some are marketed loosely. The actual pattern and performance evidence matter.
Ask for actual hearts images, arrows images, a GIA report, 360 degree video, and light performance evidence when available.
It is worth paying for when the proof is strong and the buyer values cut precision. It is not worth paying for when the label is unsupported.
