Located in London, GB
Oriented Chondrite Meteorite Circa 4.56 Billion y/o
Chondrite
24 x 20 cm, 28 cm tall on base
7.1 kg
A sculptural and beautifully weathered chondrite meteorite; upon entering the atmosphere, this extraterrestrial stone would have heated the surrounding air to a temperature of over 1700 C, higher than that of the hottest lava on the planet, and enough to melt away its outer layers, leaving its surface rippled with regmaglypts, thumb-shaped impressions formed as superheated rock streaked off of the main body as it careened toward the earth. The last layer of the rock to melt would have re-solidified as the meteorite made impact, forming a charcoal coloured fusion crust, which has taken on a deep ochre-tinted patina.
Chondrite meteorites such as this example were formed at the very beginning of our solar system, by the accretion of various types of dust and small grains, adrift in the vacuum of space and, as such, provide important clues about the birth of our own planet. This piece is an especially rare specimen, known as an oriented meteorite...

Large Chondrite Meteorite with Regmaglypts
Located in London, GB
NWA 12759
Stone, Chondrite - L5
18.3 KG
“This specimen of the NWA 12759 L5 chondrite has a smooth posterior fusion crust where meteoritic melt pooled as the rock descended through the atmosphere and was heated by friction with molecules of air. The meteorite is from the L-chondrite asteroid that was destroyed by an energetic collision 470 million years ago.”
Dr Alan E. Rubin, PhD Department of Earth, Planetary, and Space Sciences, UCLA
Detached from its parent body by a mighty impact, this large, oriented meteorite travelled over a hundred million miles through space before falling to Earth in the North African desert. Beautiful regmaglypts radiate from the apex of its cone shaped nose. These elongated dimples formed when streaks of superheated molten rock streamed off the meteor’s surface as it blazed through the atmosphere. The entire piece is coated in a glossy, umber-coloured fusion crust and close examination reveals remnants of encrusted, orange dirt.
Whilst most meteors tumble as they travel through the Earth’s atmosphere, oriented meteorites...
