A substantial end cut of NWA 18497, an oxidized CV3 carbonaceous chondrite

NWA 18497 belongs to the CV group of carbonaceous chondrites, primitive stony meteorites that preserve solids from the earliest stage of the solar system. At 71.00 grams, this end cut carries a broad polished face crowded with chondrules in copper, orange, and tan tones set against a dark olivine-rich matrix, along with a pale gray inclusion of the type that ranks among the oldest dated objects known to science. The reverse keeps the natural weathered exterior, where chondrules stand out in relief across the surface of the stone.

The Meteoritical Bulletin lists NWA 18497 as CVox3 with a total known mass of 725 grams. It was classified by J. Garcia at ADARA in the Canary Islands and carried the workname BMD 038 during study.

Structure and features

The polished face reads like a map of the early solar nebula. Chondrules average close to 1.2 millimeters in the studied section and reach larger sizes, most showing porphyritic textures in which crystals of olivine and pyroxene sit within finer groundmass. FeO-poor Type I chondrules dominate the population. Between them runs the compact, fine-grained matrix, built from micrometer-scale olivine and opaque phases, which gives the cut face its dark background.

Near one margin of the face sits a pale gray inclusion with the irregular outline characteristic of calcium-aluminum-rich inclusions (CAIs), refractory objects that condensed before the chondrules formed. The classification work on this meteorite documents CAIs from submillimeter size up to almost a centimeter, including one measuring about 9 millimeters in the studied thin section, along with amoeboid olivine aggregates in the matrix. Thin light veins thread across the stone, a record of desert exposure. On the uncut surfaces, differential weathering has etched the matrix back and left individual chondrules standing proud, so the chondritic texture can be read on the natural exterior as well as the polished interior.

Discovery and provenance

The stone was purchased from an Algerian dealer in 2024 and carries the Northwest Africa designation applied to material recovered across the Sahara without precise find coordinates. Classification was performed by J. Garcia at ADARA, Petrography and Curation of Astromaterials, in the Canary Islands, Spain, with the submission made by Jose Garcia, and the entry is published in Meteoritical Bulletin no. 115. The type specimen rests at the Museo de la Naturaleza y Arqueologia (MUNA) in Tenerife, ADARA retains a thin section, and the main mass is recorded with Brian McDonald. The Bulletin records the meteorite as a find with a low weathering grade.

Scientific context

CV chondrites take their name from the Vigarano fall and are best known through Allende, the 1969 Mexican fall that became one of the most analyzed rocks in planetary science. The group is defined by large chondrules, an abundant dark matrix, and a high content of calcium-aluminum-rich inclusions. CV chondrites divide into reduced and oxidized branches, and NWA 18497 falls on the oxidized side, assigned following the metal and sulfide chemistry framework published by Gattacceca and colleagues in 2020.

The petrographic type 3 marks an unequilibrated stone whose minerals never reached a common composition through heating. In NWA 18497 that heterogeneity is strong: chondrule olivine averages Fa8.6 while matrix olivine runs near Fa50, and the sparse metal carries nickel near 66 weight percent. These values, together with the Type I dominated chondrule population and the presence of AOAs and CAIs, anchor the stone in the CV3 group.

Frequently asked questions

What does CVox3 mean?
CV identifies the group of carbonaceous chondrites, ox marks the oxidized subgroup based on metal and sulfide chemistry, and 3 is the petrographic type, indicating material that has changed little since it formed in the early solar system.

What is the pale gray patch on the polished face?
It has the form of a calcium-aluminum-rich inclusion, a refractory object that condensed from the solar nebula before the chondrules. CAIs are documented throughout this meteorite, including one about 9 millimeters across in the classified thin section.

How is an end cut different from a slice?
A slice is taken from the interior and polished on both faces, while an end cut preserves one polished face and keeps the natural exterior of the stone on the other side. This piece shows the interior texture and the weathered outer surface in a single specimen.

Will it respond to a magnet, and how should it be stored?
It gives only a weak pull, far less than an iron meteorite, since metal is sparse and partly oxidized. Handle it with clean hands or gloves and keep it in a dry environment to protect the polished face.

Collector significance

Few specimens compress as much early solar system history into one object as a CV3: chondrules that froze from molten droplets, fine dust that became matrix, and refractory inclusions older than the planets. At 71.00 grams, this end cut offers a broad polished face for display alongside the natural exterior of the stone. As of June 2026, the Meteoritical Bulletin lists this as 1 of 64 approved meteorites classified as CVox3. This specimen is offered by Treasure Coast Meteorite Co., IMCA Member #3323.

Great for crazy pups!
Size: 8 Inch Diameter, Color: Ocean Blue
Tough and fun! This is a great toy to keep in the yard for play. I have a heavy chewer. He can get a hold of it and carry it around but it doesn't pop. It is soft enough but also strong. My dog loves to herd it around. He loves it!

Durable, bouncy fetch toy that dogs usually love
Size: 8 Inch Diameter, Color: Ocean Blue
Bouncing Dog Toy is generally very well received, especially for dogs that enjoy fetch and active play. It is made from a flexible, puncture resistant material that can handle a lot of biting and chewing without immediately popping or losing shape. Many owners like that it has a good bounce and is easy for dogs to grip, even when wet or slobbery. It is also lightweight enough for kicking, tossing, or rolling, which makes it great for interactive play sessions. A big highlight is that it floats, so it works well for water play as well as backyard or park fetch. The 8 inch size is especially good for medium to large dogs because it is big enough to avoid accidental swallowing but still easy for them to carry and chase. Most complaints are pretty typical for any dog toy of this type, meaning very strong chewers can eventually damage it, and some dogs may puncture it over time, but even then it often keeps its shape and continues to be usable

Soccer ball just for dogs
Size: 6 Inch Diameter, Color: Ocean Blue
I could say "soccer", and our shoodle would wag her tail ready to play soccer with a tennis ball so I tried out this real soccer ball with her. Mostly, she just wants to wait for me to kick it, playing defense, so she can chase it like the tennis ball. After that she wants to usually bite it or roll over on top of it as a way to secure the ball, but sometimes she will have fun pushing it around with her nose or paws. She still prefers the frisbee for play time outside since the frisbee is good for catching and for playing tug-o-war, but this is a good alternative that always gets her wagging with excitement. I wanted to get a regular 6" soccer ball for our shoodle, but this was a good choice for dogs for the durability and safety of the rubber material. The hexagons give the dog some grip to pick it up. The rubber is soft enough to grip and expel air when they do figure out how to grip it. The ball is designed to suck back in air when the dog releases the ball. - Durable rubber material ideal for dogs - Dog can squeeze out air to grip it - Ball fills back up with air after air is squeezed out - Can make more noise than a leather soccer ball - Noise is still tolerable when used indoors

Good for aggressive cheers. Reinflates everytime even when punctured
Size: 6 Inch Diameter, Color: Apple Green
I have an aggressive cheer that will tear apart anything. I bought this a few months ago and it is covered in puncture holes but it reinflates everytime. Best dog toy ever she loves it. I would buy a dozen of these. The medium size is perfect for my mini bull terrier. Big enough to not get completely in her mouth but small enough that she can still grip it to carry it around

Dog approved for fun, human approved for durability for the price.
Size: 8 Inch Diameter, Color: Orange
This has been my dogs favorite outdoor toy for years . I love these because they are durable and won't deflate when bitten or when carried around in their mouth.... no matter how many holes the dogs put in them. We leave these outside year round even in Minnesota winters. It is strong enough to hold up yet soft enough to be safe on their teeth. Now I do want to say although it is really durable it is not indescribable. IF you have a heavy chewer or a dog that loves to destroy toys, they would need supervision with this I think. My dogs don't try to chew this up but they do wear out over time. We replace it every 2 to 3 years on average. Definitely dog approved and recommended in my home, and human approved for cost and durability. I hope your dogs love it as much as mine do.
