The golden rule in the world of diamonds is that the cut is king. Color, clarity, and carat may get the spotlight in ads, but it’s the cut lines, angles, and polish that make a diamond sparkle beautifully. 

The “Triple Excellent” was considered the gold standard for quite some years. It is a diamond with excellent cut, polish, and symmetry you could ever hope for. But what if there’s more to the story? 

The 8X cut diamond is a precision-driven, optically superior evolution in diamond cutting that considers eight exacting factors instead of four. It’s about going deeper, literally and figuratively, into what makes a diamond not just brilliant, but exceptional.

We, at Ouros Jewels, have recently added 8X cut diamonds to our collection, and it’s time to understand what makes them unique from the other EX diamonds.   

What Makes an 8X Cut Different? 

An 8X cut diamond is graded on eight critical aspects of craftsmanship:

    1. Polish: This is the surface quality. Any tiny blemish or abrasion can scatter light and dull the shine. Flawless polish means uninterrupted sparkle.

    2. Symmetry: Each facet must be precisely aligned. If symmetry is off, light doesn’t reflect evenly, and the sparkle loses its rhythm.

    3. Table Percentage: The table is the flat top of the diamond. Too big or too small, and the diamond won’t return light properly.

    4. Depth Percentage: Depth determines how deep or shallow the diamond is. Ideal depth keeps light bouncing inside the stone before it exits your eye.

    5. Crown Angle: The crown is the upper portion of the diamond. Its angle affects how much fire (those rainbow flashes) you see.

    6. Pavilion Angle: This is the angle of the bottom facets. A perfectly angled pavilion returns light upward. Too shallow or steep, and you can say goodbye to brilliance.

    7. Star Length: These are the skinny facets that point toward the center of the table. Ideal star length helps focus light toward the middle of the stone.

    8. Lower Half Length: Located below the girdle, these facets influence how the diamond sparkles when tilted. The longer and more balanced they are, the more movement and life the diamond shows.

These additional details go beyond the standard GIA criteria to evaluate how light actually moves through the diamond and how much brilliance, fire, and scintillation it delivers as a result.

Think of it like upgrading from a high-definition screen to 4K Ultra HD. The extra layers of refinement aren’t always visible at first glance, but once you see the difference, you can’t unsee it.

Factor 8X Cut Diamonds 3X Diamonds

Brilliance Superior light reflection Excellent, but slightly less than 8X cut
Facet Precision Each facet’s angle is meticulously calculated Standard facet proportions
Symmetry Near-perfect symmetry with minimal variance No precise angle calibration
Light Return Maximum High
Price Higher More affordable
Certification Independent certification based on exacting standards Certified for ideal proportions and symmetry
Polish Exceptional surface finish with minimal blemishes, enhancing overall light performance Very good polish, but may allow for minor surface imperfections

What is The Science Behind the Sparkle of 8X Cut Diamonds? 

Diamonds don’t shine on their own. They borrow light, bend it, bounce it, and throw it back in ways that stop people mid-sentence from its dazzle. 

When light enters a diamond, it reflects off the inner surfaces and exits through the top. This bounce-around process is called light performance, and it’s what gives a diamond its three core personalities: brilliance (white light), fire (rainbow flashes), and scintillation (those sparkly little flashes when you move it). But all of that depends on how the diamond is cut and how light moves inside. 

Even one misstep in the angles or depth can leak light out of the sides or bottom, making a diamond look dull or dark. That’s why the 8X standard matters. It offers optimized sparkle that is engineered, intentional, and designed to perform like a prism under pressure. 

How are 8X Cut Diamonds Graded and Certified? 

Not all sparkles are created equal, and neither are the systems used to measure it.

The 8X cut grading process isn’t a marketing term or industry buzzword. It’s a performance-based promise, evaluated across eight separate cutting parameters, while labs like IGI and GIA independently grade diamonds for the traditional 4Cs and basic cut quality, the full 8X cut certification is provided by specialized labs like GCAL, which conduct in-depth optical and light performance testing. These parameters usually include things like polish, symmetry, proportions, and overall craftsmanship.

But what makes 8X unique is the rigor behind the label. Each diamond undergoes microscopic analysis and optical imaging to evaluate how well it handles light. Experts measure angles, table size, pavilion depth, and crown height. Every facet counts when testing these diamonds.

Once a diamond aces all eight categories, it’s granted the 8X distinction and accompanied by a detailed certificate outlining its cut precision and performance data.

So when you see that 8X mark, you’re looking at a standard of excellence, earned through meticulous cutting and rigorous review. It's the closest thing the diamond world has to a gold star for brilliance.

How to Recognize the Excellence of an 8X Cut Diamond

At Ouros Jewels, we believe in providing more than just a beautiful diamond, we offer you confidence in every purchase. That’s why each of our 8X cut diamonds comes with a GCAL (Gem Certification & Assurance Lab) certificate, absolutely free of charge.

GCAL is one of the most trusted names in diamond grading. Their comprehensive certification process evaluates every aspect of the diamond, from cut to clarity and light performance to ensure you receive exactly what you're investing in. The GCAL certificate guarantees that your diamond meets the rigorous standards of quality, precision, and brilliance.

But Telling the difference between a regular brilliant cut and an 8X cut isn’t always easy with the naked eye. Sparkle is subjective, after all.

So there are a few smart ways to spot a true 8X cut diamond and shop with confidence.

  1. Start with the certification

    A legitimate 8X diamond will be graded by a reputable lab, with a full report showing excellence in all eight cut parameters. Look for grades like “Excellent” or “Ideal” across polish, symmetry, table size, crown angle, pavilion depth, and other important features. 
  2. Ask to see the light performance results

    Tools like the Hearts and Arrows viewer or ASET (Angular Spectrum Evaluation Tool) reveal how the diamond handles light. An 8X cut will show exceptional brightness, fire, and contrast symmetry with fewer dark spots and more dazzle.
  3. Compare side by side

    When viewed next to a standard cut, 8X diamonds often “pop” more. Their precision cutting allows for better light return, which means they tend to sparkle more even in low light.

An 8X diamond is about how it’s been engineered to perform at its brightest. Always ask questions, request certification, and trust your eyes.

Why 8X Cut Diamonds May Appeal to Certain Buyers

Some want size. Others want sparkle. But for a growing number of shoppers, the story is in the precision, and that’s exactly why the 8X cut is preferred.

These diamonds are engineered for symmetry and perfection across eight specific cut parameters. That appeals to buyers who appreciate craftsmanship, not just carat. Or who values performance under a spotlight, not just in a display case.  

An 8X cut may also resonate with those shopping for heirlooms. These diamonds are made to last and to hold value. The meticulous standards involved in the cutting process make them a rare breed, often appealing to collectors and connoisseurs who want more than a generic “Excellent” grade. 

There’s also the emotional pull. When you give or invest in a diamond that’s cut to such rigorous standards, it says something about your taste and what you value. 

So while not everyone may need an 8X cut, the ones who choose it usually know exactly why they did.
