A 3.1-Carat Diamond Discovered at Crater of Diamonds State Park

Last month, Micherre Fox, a 31-year-old from Manhattan, New York, made a remarkable discovery at Crater of Diamonds State Park in Arkansas. Fox unearthed a 2.3-carat diamond, making it the third largest diamond found at the park in 2025 [6].

The Crater of Diamonds State Park is a unique gemstone-hunting destination, being the only diamond mine in the world open to the public [7]. It sits on an eroded volcanic pipe that was formed around 95 to 100 million years ago by a violent volcanic eruption [1][3][5]. This eruption brought diamond-bearing lamproite magma from deep within the Earth's upper mantle to the surface.

The Geology Behind the Diamond Formation

The diamonds found at the Crater of Diamonds State Park originated deep in the Earth's mantle, approximately 150–200 km below the surface. Here, extreme pressures (around 5 gigapascals) and temperatures (~1000 °C) facilitated carbon atoms bonding in a cubic crystal lattice to form diamonds [1][4]. The carbon source involved upper mantle carbon dioxide and carbon monoxide reduction reactions, as proposed by research [1][3].

The lamproite magma sampled these ancient diamonds and violently erupted to the surface about 95-100 million years ago, creating the crater now accessible at the surface [1][3][4]. Unlike faster-moving magmas, the lamproite magma here was relatively static, causing many small diamonds rather than fewer large ones to form [2].

Over time, erosion of the volcanic crater exposed the diamonds, allowing them to concentrate near or at the surface. However, their journey through chemically corrosive materials and slow transport reduced the diamond sizes and rounded their shapes, explaining why Arkansas diamonds are typically small and well-rounded [2].

A Unique Diamond-Bearing Site

The Crater of Diamonds State Park is notable for being one of the only diamond-bearing lamproite deposits in the world accessible for public prospecting, making it unique both geologically and recreationally [1][5]. Since the early 20th century, over 75,000 diamonds have been unearthed here [8].

The discovery of Fox's diamond adds to the park's rich history of gemstone finds. In 2025, at least 366 diamonds have been registered at the park [9]. Fox initially thought her find was a dew-covered spiderweb, but upon closer inspection, she realised it was a diamond [6].

Fox's statement mentioned that money can run out in a marriage and hard work is necessary to solve problems [10]. Despite this, her discovery at the Crater of Diamonds State Park could indicate a promising start to finding the perfect diamond for an engagement ring.
