The rarest fantasy cut in fine gemstones — and why every alternative bride (and groom) is obsessed with them right now.

Quick Answer:  A Starbrite™ cut is the trademarked name (by John Dyer) of a proprietary fantasy gemstone cut featuring a complex, star-like pattern of precision concave cuts on the underside of a stone. Invented by lapidarist Dalan Hargrave and commercialized by John Dyer, these cuts make a gemstone appear to glow from within. Fewer than 10 lapidaries in the world cut true star fantasy cuts using Dalan's original technique, making them exceptionally rare. The term Starbrite™ is trademarked by John Dyer, all other cuts using Dalan's technique are considered fantasy cuts. We call them star fantasy cuts.

What Is a Star fantasy Cut?

A Star fantasy cut or John Dyer's Starbrite™ cut — is a style of lapidary artistry that goes far beyond standard faceting to create something truly extraordinary. Where a traditional gemstone relies on flat, angled facets to reflect light, a star fantasy cut and a Starbrite™ cut features a complex, star-shaped pattern of precision concave cuts on the underside (pavilion) of the stone. The result is a gem that doesn't just sparkle — it appears to radiate light from deep within, like a tiny glowing star captured in crystal.

Fantasy cuts like the Starbrite™ are sometimes called 'concave cuts' or 'designer cuts' in the gem world. But the Starbrite™ or star fantasy cut is distinctive: it is a proprietary technique with a specific visual signature — that unmistakable starburst of light that seems to come from inside the stone rather than bouncing off its surface.

In simple terms:  A Starbrite™ or star fantasy cut makes your gemstone look like it's lit from within. It's not just sparkle — it's depth, dimension, and pure magic.

Who Invented the Star fantasy cut?

The Star fantasy cut was invented by lapidarist Dalan Hargrave, who developed a proprietary technique that produces the cut's signature luminous, star-like effect. Dalan's method is deeply skilled and not easily replicated — it requires a mastery of concave cutting, an extraordinary eye for precision and an enormous amount of patience for polishing.

John Dyer, one of the most celebrated names in precision gem cutting and the founder of John Dyer Gems, later commercialized and star fantasy cut and brought it to a much wider audience. The Starbrite™ name is trademarked by John Dyer & Company. Dyer's variations of the cut have won 11 different gem cutting awards.

Dalan Hargrave went on to teach his technique to other lapidaries. Today, roughly 50 of his students work in fantasy cutting — but only about 10 or fewer are executing the star fantasy cut specifically using Dalan's original method. That is a vanishingly small number for a cut that is generating this much excitement in the gem world right now.

How Is a star fantasy Cut Made?

A star fantasy cut is applied to the pavilion — the bottom, pointed portion of the gemstone that faces downward when set in a ring. Instead of traditional flat facets, the lapidary cuts a complex, radiating pattern of concave grooves. These grooves catch light from multiple angles simultaneously and scatter it back through the stone in that signature starburst glow.

The technique Dalan Hargrave developed is proprietary, meaning it can't simply be copied from a diagram or formula. It requires deep training, refined instinct, and a lot of patience.

More recently, a machine called the Ultratek has been developed that can apply the star fantasy pattern mechanically. Some talented lapidaries — including The Fellowship Forge and Geologic Spectrum — are working with this technology. However, the machine can only put in the cuts. The true artistry lies in polishing those cuts to perfection, which remains entirely dependent on the skill of the cutter's hands.

How long does it take? 

Cutting and polishing a star fantasy cut into a sapphire takes approximately half a day to a full day of continuous work. Sapphires are a 9 on the Mohs hardness scale, making them extraordinarily durable — and extraordinarily time-consuming to cut.

What Gemstones Can Be Cut in the Star Fantasy Cut Style?

Fantasy cuts can be applied to most gemstones, with one notable exception: diamonds, which are too hard for the concave cutting technique to be applied effectively. However, with the recent advances in cutting technology and lasers, it’s only a matter of time before diamonds can join the party.

Some of the most stunning star fantasy cuts appear in:

• Sapphires (blue, teal, parti, Montana, color-change)
• Tourmaline
• Aquamarine
• Garnet
• Citrine and Ametrine
• Beryl
• Zircon
• Sunstone

For engagement rings specifically, we focus on stones rated 9 or above on the Mohs hardness scale — which means sapphires are our primary love. They offer the durability required for a ring worn every single day, and a star fantasy cut transforms an already gorgeous sapphire into something otherworldly.

Star Fantasy Cut Sapphires: Our Favorites at Bohemi

Not all sapphires are created equal, and the star fantasy cut has a remarkable ability to amplify what makes each variety unique. Here are the sapphire types we're most obsessed with:

Australian Parti Sapphires

Parti sapphires display two or more distinct colors within a single stone — often vivid combinations of teal, yellow, blue, and green. When a star fantasy cut is centered precisely beneath a parti sapphire's natural color zoning, something magical happens: the star-like cut pattern aligns with the color boundaries and amplifies them, making the stone appear to bloom with color from the inside out. It's one of the most visually stunning combinations in all of alternative gemstone jewelry.

Montana Sapphires

Montana sapphires are mined in the mountains to our north and are beloved for their gradient color shifts — often moving from deep blue to bright teal or blue-green with the most breathtaking gradation. Looking into a Montana sapphire with a star fantasy cut is like watching sunlight stream through ocean water at different depths. The cut amplifies the color transition in a way that feels alive and constantly changing with the light.

Dragon Sapphires (Color-Change Sapphires)

Dragon sapphires are color-changing sapphires that shift in hue depending on the light source — appearing one color in daylight and something entirely different under incandescent light. They're already one of the most mysterious gemstones in existence. Add a star fantasy cut to the underside, and that mysterious stone takes on a fiery, glowing depth that makes it look almost sentient. For anyone drawn to drama, magic, and the utterly unforgettable, a Dragon sapphire with a star fantasy cut is the engagement ring stone of your dreams.

Where We Source Our Star Fantasy Cuts

At Bohemi, we are particular about where our fantasy cuts come from — because the quality of the cutting and polishing makes all the difference. We source exclusively from two lapidaries we trust completely:

Brett Kosnar of Kosnar Gems

Brett's attention to detail on the polished surfaces of the underside cuts is, quite simply, unmatched. The care he takes on each individual facet of the star pattern results in a stone whose sparkle is rich, dimensional, and absolutely breathtaking in person. It's an added delight that Brett is a fellow Coloradoan — and supporting a local artisan who also happens to be world-class is something we never take for granted. Brett has been in the gem world his whole life, his family even has a gemstone named after them: Kosnarite. He's won multiple AGTA Cutting Edge Awards for his fantasy cutting and is our go-to for custom cutting. 

John Dyer of John Dyer Gems

John Dyer is one of the most recognized names in precision gem cutting worldwide. His Starbrite™ cuts are award-winning, technically masterful, and deeply beautiful. His work helped bring the star fantasy cut technique to a global audience, and the quality of his stones speaks for itself.

How Rare Are Star Fantasy Cut Stones?

Genuinely rare. And here's exactly why:

• Fewer than 10 lapidaries in the world cut true star fantasy cuts using Dalan Hargrave's original proprietary technique
• Each sapphire star fantasy cut requires half a day to a full day of continuous skilled labor
• Sapphires are a 9 on the Mohs scale — among the hardest stones to cut
• These are not mass-produced gems — every single star fantasy cut stone is a handcrafted original
• High demand + low supply = stones that sell out fast and are not easily replaced

If you've spotted a Starbrite™ or star fantas cut stone you love, don't wait. They move quickly — and they don't come back.

Are Starbrite™/Star Fantasy Cuts Good for Engagement Rings?

Short answer:  Yes — emphatically yes, as long as you choose the right stone. A star fantasy cut sapphire (Mohs 9) is an excellent engagement ring stone: durable enough for daily wear, one-of-a-kind by nature, and unlike anything available in a traditional jewelry store.

Starbrite™/Star Fantasy cuts work beautifully for both women's and men's engagement rings and wedding bands, and they come in all shapes and sizes — rounds, ovals, pears, hexagons, marquis, rectangles, and more. The cut adds visual interest and dimension to every shape.

A shallow star fantasy cut sapphire also offers a practical benefit: a larger face size for the carat weight, and a lower profile when set in a ring — meaning less snagging and less exposure to everyday knocks. That's a meaningful advantage for a stone you'll wear every day for the rest of your life.

Frequently Asked Questions About Starbrite™/Star Fantasy Cuts

What is a Starbrite™/Star Fantasy cut gemstone?

A star fantasy cut is a fantasy gemstone cut featuring a complex, star-shaped pattern of concave cuts on the pavilion (underside) of the stone. The cut was invented by lapidarist Dalan Hargrave and the Starbrite™ name was trademarked by John Dyer. It makes the stone appear to glow with light from within.

Who invented the star fantasy style of cutting?

The star fantasy cut was invented by lapidarist Dalan Hargrave, who developed a proprietary cutting technique that produces the style's signature internal glow. John Dyer later commercialized the cut and holds the trademark for the Starbrite™ name.

Is the Starbrite™ or star fantasy cut the same as a fantasy cut?

The Starbrite™ cut is a type of fantasy cut — meaning it uses non-traditional, concave faceting to create a decorative effect beyond standard gem brilliance. However, the star fantasy cut is a specific, proprietary technique with a distinct visual signature, not a generic term for all fantasy cuts, and Starbrite™ is the trademarked name for John Dyer's star fantasy cut. 

Can star fantasy cuts be applied to diamonds?

No, or we should say, not yet. Diamonds and moissanite are too hard for the star fantasy concave cutting technique. The cut works on most other gemstones, including sapphires, tourmaline, aquamarine, garnet, citrine, and beryl.

How much does a Starbrite™ or star fantasy cut sapphire cost?

Starbrite™ and star fantasy cut sapphires vary widely based on size, color, and cutting quality. Given that each stone requires half a day to a full day of skilled labor to cut, and only a handful of lapidaries in the world do this work, they command a premium over standard-cut sapphires. They are rare, handcrafted objects — and priced accordingly.

What is the difference between a star fantasy cut and a regular sapphire cut?

A standard sapphire cut uses flat, angled facets on the pavilion to reflect light. A star fantasy cut uses a complex, radiating pattern of concave grooves instead, which causes light to scatter and glow from within the stone rather than simply reflecting off its surface. The visual effect is dramatically different — deeper, more luminous, and unlike anything a traditional cut produces.

Are star fantasy cuts durable enough for everyday wear?

Yes, when applied to sapphires (Mohs hardness 9). Sapphires are one of the hardest gemstones available and are well-suited for daily wear in engagement rings. The Starbrite™ or star fantasy cut does not compromise the stone's structural integrity.

Where can I find Starbrite™ or star fantasy cut sapphires for an engagement ring?

The best way to find a Starbrite™ or star fantasy cut sapphire for an engagement ring is through an independent jeweler who sources directly from the cutters — like Bohemi.

What is a Dragon sapphire?

Dragon sapphires are color-changing sapphires — gems that shift in color depenstar fantasy cut, the stone takes on an added fiery depth that amplifies its mysterious color-shifting quality.

How rare are Starbrite™ or star fantasy cuts?

Extremely rare. Fewer than 10 lapidaries in the world cut star fantasy cuts using Dalan Hargrave's original technique. Each stone takes half a day to a full day to cut, and demand significantly outpaces supply. True star fantasy cut stones are one-of-a-kind and sell out quickly.
