Here is another unusual presentation of a lunar sample. In December 2019, approximately 400 kilometers from Timbuktu, a clutch of unusual dark stones were discovered in the wadi of Tisserlitine. Most of these stones were very small, but the largest, 40.026 kilograms (88 lbs), was at one time the second largest piece of the Moon on Earth — and it’s from the very same Moon rock that this partial slice is derived. The Moon is among the rarest substances on our planet. Less than 2000 kilograms of lunar meteorites are known to exist. All would fit in the back of a small pick-up and a significant portion of these rocks is controlled by governmental institutions. Not one milligram of the nearly 400 kilograms of the Moon returned to Earth by Apollo astronauts is available for private ownership. Lunar meteorites are delivered to Earth after being blasted off the lunar surface following the impact of an asteroid or comet. As a result of the ongoing pulverization of the lunar surface, different presentations of brecciation and melting are seen — no other lunar samples look quite like Tisserlitine 001. Cut on two edges, one side of this partial slice is highly polished. The meteorite's external surface is seen on a curved rim. A palette of grays and charcoals with signature white anorthositic clasts are seen in the fine-grained matrix primarily composed of anorthite, olivine, pigeonite, augite and orthopyroxene. Small vents and divots characteristic of Tisserlitine are in evidence, as are tiny flecks of metal derived from an impacting asteroid — one of many such impactors that provided the Moon with its craters. Now offered is an exemplary large format specimen of the Moon. The analysis of this meteorite was led by Dr. Anthony Irving, whose findings underwent peer review by the Nomenclature Committee of the Meteoritical Society. The analysis and classification were published in the 109th edition of the Meteoritical Bulletin, the official registry of meteorites. Christie's
