ADMIRE — EXTRATERRESTRIAL PERIDOT IN EVIDENCE IN COMPLETE SLICE
Admire is a member of the pallasite group of meteorites, widely considered to be the most beautiful of all meteorite varieties. Pallasites formed at the mantle-core boundary of an asteroid as grains of stony olivine (a magnesium-rich silicate mineral) settled atop the molten iron core. Gem-quality olivine is also known as the semi-precious gemstone peridot (the August birthstone)—and both are featured in this specimen. The olivine grains in Admire are somewhat rounded and somewhat angular, indicating that the rock was heated and recrystallized after it formed. Originating from the asteroid belt, the first two masses of Admire were ploughed up in 1881.
Christie's would like to thank Dr. Alan E. Rubin at the Institute of Geophysics and Planetary Physics, University of California, Los Angeles for his assistance in preparing this catalogue note.

DEEP IMPACT: MARTIN, LUNAR AND OTHER RARE METEORITES
Polished to both sides, one with mirrored finsihed the other etched. In very good condition. Please note that weights and dimensions are approximate only and that the appearance and surfaces of meteorites can change with atmospheric conditions. Specifically moisture, and salts and acids from excessive handling, can be lightly corrosive and accelerate the natural patination of the meteorite.
The condition of lots sold can vary widely due to factors such as age, previous damage, restoration, repair, and wear and tear. The nature of the lots sold means that they will rarely be in perfect condition. Lots are sold in the condition they are in at the time of sale.
