Lot 2 | NWA 12691 — A POCKETSIZE PIECE OF THE MOON, INTERIOR AND EXTERIOR REVEALED
Estimate value
$ 5 000 – 8 000
This is a lunar meteorite — that is to say, a piece of the Moon ejected from the lunar surface following an asteroid impact — that was cut and polished to reveal its matrix. The analysis performed by researchers to confirm its lunar origin was vetted by a panel of colleagues prior to publication in the bible of meteorites — the Meteoritical Bulletin. Lunar specimens are identified by specific geological, mineralogical, chemical and radiation signatures. Many of the common minerals found on Earth’s surface are rare on the Moon; in addition, lunar rocks contain gases originating from the solar wind with isotope ratios that are markedly different than the same gases found on Earth. Finally, lunar samples brought to Earth by the Apollo missions are closely similar to suspected lunar meteorites and this is one such example. Fragments of the Moon are the rarest substances on Earth and now offered is a durable pocket-sized example. See lot 56 for a microscopic image of NWA 12691. For more on lunar meteorites and NWA 12691 in particular, see lots 14 and 55.

Christie's would like to thank Dr. Alan E. Rubin at the Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles for his assistance in preparing this catalogue.

This meteorite was analyzed and classified by Dr. Anthony Irving at the University of Washington and his findings underwent peer review prior to publication in the 108th edition of the Meteoritical Bulletin.
