A brown stone the size of a gumball, pulled from red mud on a January afternoon
A French traveler, extending a spontaneous road trip through the American South, stumbled upon one of the rarest gifts the earth quietly offers: a 7.46-carat brown diamond pulled from the mud of a 100-million-year-old volcanic field in Arkansas. Julien Navas had no particular expertise, only curiosity and fortunate timing — arriving just after heavy rains had stripped away the topsoil and exposed what lay beneath. His find at Crater of Diamonds State Park ranks among the largest ever made by a casual visitor, a reminder that the planet's deep history occasionally surfaces in the most democratic of places, available to anyone willing to look.
- A chance detour — born from a rocket launch and a traveler's restlessness — led a Parisian tourist to one of the only public diamond fields on Earth.
- Hours of fruitless digging gave way to a single surface scan, and a small brown stone that simply looked wrong among all the others.
- Park staff confirmed the near-impossible: a genuine 7.46-carat brown diamond, the eighth largest found by a visitor since 1972.
- The discovery was not pure luck — heavy rains days earlier had eroded the topsoil, a geological pattern park staff say reliably triggers spikes in finds.
- Navas named the stone Carine, after his fiancée, and plans to have it cut into jewelry for her and their daughter — a volcanic relic turned family heirloom.
- He has already said he intends to return, suggesting the earth's slow generosity, once experienced, is difficult to walk away from.
Julien Navas had not planned to go to Arkansas. The French tourist had traveled to Florida to watch a rocket launch, and when the mission succeeded, he extended his American road trip before heading home to Paris. Somewhere in the South, he heard about a park where anyone could dig for diamonds and keep what they found. Curious enough to make the detour, he arrived at Crater of Diamonds State Park in Murfreesboro on January 11, 2024.
The timing was quietly extraordinary. Heavy rains had fallen just days before, softening the ground and stripping away topsoil across the 37.5-acre volcanic field. After hours of digging without result, Navas shifted his approach and began scanning the surface instead — and there it was: a small brown stone that looked unlike everything around it.
Park staff confirmed it was a genuine diamond. At 7.46 carats, deep chocolate in color and rounded in shape, it became the eighth largest stone ever found by a visitor since the park opened to public hunting in 1972. The site sits atop a lamproite pipe — a volcanic structure that carried diamonds from the Earth's depths to the surface roughly 100 million years ago. More than 75,000 diamonds have been recovered there since 1906, with over 600 found by tourists in an average year. Most are tiny. Navas's was not.
Park staff noted that the pattern is well established: significant rainfall exposes buried stones, and finds tend to spike in the days that follow. Navas had arrived at precisely the right moment, when nature had already done much of the work.
He named the diamond Carine, after his fiancée, Carine Eizlini, and plans to have it cut and set into jewelry for her and their daughter. In interviews, he described the discovery as the kind of thing you assume happens to other people. He also said he intends to return to Arkansas someday — because once the earth has offered you something like this, it seems, you don't entirely stop looking.
Julien Navas was supposed to be heading home to Paris. The French tourist had come to Florida to watch the Vulcan Centaur rocket launch, and after the mission lifted off, he decided to extend his American road trip before crossing the Atlantic. Somewhere along the drive through the South, he heard about a place in Arkansas where ordinary visitors could dig for diamonds and legally keep whatever they found. It sounded like a long shot, but he was curious enough to make the detour.
On January 11, 2024, Navas arrived at Crater of Diamonds State Park in Murfreesboro, Arkansas, rented a basic diamond-hunting kit, and got to work. The timing turned out to be fortunate. Heavy rains had soaked the region just days before—more than an inch had fallen—leaving the ground soft and muddy. After spending hours digging without success, he abandoned the deeper excavation and began scanning the surface instead. That's when he spotted a small brown stone that looked different from everything else around it.
When park staff examined the find at the identification center, they confirmed what seemed almost impossible: a genuine brown diamond, 7.46 carats, rounded in shape with a deep chocolate color. The stone had entered the record books as the eighth largest diamond discovered by a visitor since the park opened to the public in 1972. For context, the largest diamond ever found in the United States—the legendary Uncle Sam Diamond—came from this same volcanic formation and weighed over 40 carats. Other notable finds included the Amarillo Starlight at 16.37 carats and the Esperanza Diamond at 8.52 carats. Navas's discovery ranked among the rarest outcomes a casual visitor could hope for.
The park exists because of geology that reaches back 100 million years. The land sits atop what geologists call a lamproite pipe—a volcanic structure formed by ancient eruptions that brought diamonds from the extreme depths of the Earth up toward the surface. Since 1906, when systematic searching began, more than 75,000 diamonds have been recovered from this 37.5-acre field. In an average year, over 600 stones are found by tourists and amateur hunters using simple tools like shovels and sieves. Most are tiny. Navas's find was exceptional.
The heavy rains that had made the ground so difficult to work actually created the conditions for discovery. Erosion from the water had washed away topsoil and exposed stones that had been buried just beneath the surface. Park staff explained that this pattern repeats regularly—after significant rainfall, the number of finds tends to spike. Navas had arrived at exactly the right moment, when nature had done half the work for him.
He named the diamond Carine, after his fiancée, Carine Eizlini. According to reports from the park and American media, he plans to have the stone cut and crafted into jewelry for his future wife and their daughter. In interviews, Navas described the discovery as almost unbelievable—the kind of thing that happens to other people, not to you. He also said he intends to return to Arkansas someday to try his luck again. For now, a brown stone the size of a gumball, pulled from red mud on a January afternoon, will become a family heirloom.

What made him stop at this particular park? It seems like a random choice.
It wasn't entirely random—he'd heard about it during his travels. But yes, it was a detour. He was already in the country for the rocket launch, already committed to driving around. The park was just something that caught his attention, and he had time.
And the timing with the rain—was that pure luck, or did he know the conditions would be good?
Pure luck. He didn't plan it that way. The rains had come days before he arrived. He just happened to show up when the ground was still soft and exposed. If he'd come a week later, the surface would have dried and settled again.
Six hundred diamonds a year sounds like a lot. Why is his find so rare?
Size. Most of those 600 are tiny—flecks, really. His stone is nearly eight carats. That puts him in the top eight discoveries in over fifty years. The difference between finding a diamond and finding a *significant* diamond is enormous.
He named it after his fiancée. Does that change what it means to him?
It transforms it. It's no longer just a geological curiosity or a lucky find. It becomes a story he'll tell forever, and eventually a piece of jewelry his family will wear. The naming makes it personal.
Will he actually go back?
He said he would. Whether he does is another question. But the experience clearly affected him. He described it as almost unbelievable. That kind of amazement tends to pull people back.
