NWA 12691 — THE LUNAR BRACELET

The Moon – lunar feldspathic breccia; Sahara Desert, Mauritania

Estimation : 60000 - 90000 USD


The Moon is among the rarest substances on our planet. Less than 2500 kilograms of the Moon is known to exist on Earth and every single bit could fit in the back of a small pick-up truck. While Apollo astronauts returned with 382 kg of Moon rocks, not one milligram of this material is available for private ownership. As for the nearly 2000 kg of lunar meteorites, i.e., pieces of the Moon ejected off the lunar surface by asteroid impacts (and nearly all of the craters on the Moon are the result of such hypervelocity collisions), a good deal of that material is also untouchable as a result of its residency in the world’s great museums and research institutions. Scientists identify Moon rocks by specific textural, mineralogical, chemical, and isotopic signatures. Many of the common minerals found on Earth’s surface are rare or absent on the Moon and some lunar minerals are unknown on Earth. In addition, Moon rocks contain gases captured from the solar wind with isotope ratios very different from the same gases found on Earth. As one would expect, many of the Moon rocks returned by Apollo missions are nearly identical to lunar meteorites — and such is the case with NWA 12691. For a meteorite to be officially considered a meteorite it must be published in the scientific journal of record, the Meteoritical Bulletin. The protocol commences with the analysis of a specimen which then undergoes peer review by scientists on the Nomenclature Committee of the Meteoritical Society. As there needs to be a system to identify specimens, the Committee chooses a name for the rock after the location to which it was “delivered,” (e.g., a city, village, mountain, river, district, etc.). In a desert, where there are few distinguishing landmarks, meteorites are named for the designated region with sequential numbering. Found in 2017 by desert nomads, NWA 12691 is the 12,691st specimen to be assigned a number after it was recovered from the North West African corridor of the Sahara Deser
