NWA 7325

Discovered in southern Morocco in 2012, NWA 7325 is one of the most visually striking and scientifically intriguing meteorites ever found. With its vibrant emerald-green hue and fine-grained texture, this rare achondrite immediately drew the attention of scientists and collectors around the world. What sets NWA 7325 apart is not only its unique appearance but also its chemical composition, which hints at an extraordinary origin—possibly the planet Mercury.

Composed primarily of magnesium-rich silicate minerals and exhibiting an unusually low iron content, NWA 7325 differs significantly from most known meteorites. These characteristics align closely with what scientists expect from Mercury’s surface, based on data from NASA’s MESSENGER spacecraft, which orbited Mercury from 2011 to 2015. This potential link to Mercury is especially exciting, as no confirmed meteorite from Mercury has ever been identified. If proven, NWA 7325 could be the first and only known sample of Mercury’s crust available for study on Earth.

The meteorite was studied extensively at the University of Washington and other leading research institutions, where detailed isotopic and mineralogical analyses were performed. The results confirmed its exotic nature, but the debate regarding its exact planetary origin remains open. While some researchers lean toward a Mercurian source, others suggest it may have come from a differentiated asteroid with characteristics similar to Mercury’s surface.

Regardless of its origin, NWA 7325 remains one of the most exotic and scientifically valuable meteorites in existence. Its rich green coloration, rarity, and mysterious history make it highly prized not only by planetary scientists but also by collectors and museums worldwide. As research continues, this remarkable stone may yet reveal more secrets about the early Solar System and the processes that shaped the rocky planets. Whether from Mercury or a yet-unidentified body, NWA 7325 is a true gem among meteorites—both literally and figuratively.
