The rarest of the three main types of meteorites, the stony-irons are divided into two groups: the mesosiderites and pallasites. Mesosiderites are believed to have been formed by violent asteroidal collisions, millions of year ago in deep space. Pallasites are made of roughly 50% nickel-iron and 50% green olivine crystals. Olivine is also known as the gemstone peridot. When sliced, pallasites can be colorful and even translucent and have an extraordinary otherworldly beauty. Of the approximately 60,000 officially recognized meteorites only about 300 are pallasites, making them rarer than diamonds or even emeralds. When you hold a pallasite in your hand, you are literally holding gems from outer space!

Pallasite-PMG, Found in Kansas, 1881
We, at Aerolite, love all pallasites — but Admire is quite close to our hearts. It’s name made waves when our hosts Geoff Notkin and Steve Arnold pulled a hefty 223-pound “Alpha” (Admire) pallasite out of the ground on Season Two, Episode One of Meteorite Men. Not to worry! That monster made it through the back-and-forth between Geoff and Steve and remains intact. These lovely part slices and “nuggets” are from the same strewnfield, but altogether different rock. The part slices were expertly prepared. They are beautifully appointed, with etch on one side and polish on the other. The “nuggets” are created when the pallasite is being stabilized. They truly look like visitors-from-outer space!
Pallasite, Found in United States, 1882
The Brenham meteorite was first discovered during the 1880s inÂ Kiowa County, Kansas by the wife of a frontier farmer. Numerous additional masses were found in the years that followed. Brenham, Kansas became a world-famous meteorite locality when the pilot episode of the television series Meteorite Men was filmed there and several large masses were recovered. Brenham is an olivine-rich pallasite, comprised of approximately 50% nickel iron and 50% olivine (peridot). Brenham is known for its jade-green, oval, coffee bean-shaped crystals. We are currently out-of-stock on our Brenham.
Mesosiderite-B4, Found in the Philippines, 1956
The story of the Bondoc mesosiderite is one of the most remarkable in meteorite history. Recovered by H.H. Nininger 40 miles from the nearest village in a remote part of the Philippines during the 1950s, the original, and only, mass weighed a staggering 1,955 pounds. At the time, it was the second largest stony-iron meteorite ever found. It took Nininger nearly four years to get the mass back to the United States, and its amazing journey included travel by bulldozer and river raft.
Examples of this material are described as Bondoc nodules. Some of the matrix survived in excellent condition. Some of it was cut into slices, and others were preserved in their natural state. We are very pleased to have examples of both. These are described as Bondoc silicates.
Since Nininger transported the original mass from the Philippines, we can say Bondoc has Nininger provenance, even though not all specimens carry a hand-painted number.
Pallasite, Found in Russia, 1810
First discovered in Belarus, Brahin is among the most alluring of pallasites. Some years ago, we acquired a large mass from an old collection and sent it to the lab for preparation. These astounding slices are the result. Displaying rich, sea-green olivine (peridot) crystals, these outstanding full slices show the highest olivine density (approximately 80%) of any specimens we have ever had the pleasure of offering, with colorful crystals appearing suspended in a delicate lattice of shiny metal. Cut thin for maximum translucency, and expertly prepared in one of the world’s top labs to show off their bright nickel-iron matrix, these exquisite specimens stand out as some of the most amazing examples of one of the most beautiful pallasites.

Pallasite, Found in China, 2000
An extremely beautiful pallasite characterized by extraordinarily large and colorful olivine crystals. The main mass was discovered in 2000, and this meteorite has rapidly become a favorite among collectors due to the stunning and enormous olivine crystals. The absolute finest display piece.
Pallasite, Found in China, 1884
First discovered in the late 19th Century, Glorieta is one of the most remarkable and desirable American meteorites. The Glorieta strewnfield’s terrain is notoriously rugged and difficult to navigate and, over the years, scouring its steep and dangerous slopes has been a right of passage for the most determined of meteorite hunters. We are delighted to feature absolutely spectacular complete slices of Glorieta Mountain with a brilliant etch and large dark crystals. As Widmanstatten Patterns go, this is one of the very best there is.
Pallasite, Found in Chile, 1822
The high Atacama Desert in northern Chile is one of the driest and most desolate places on Earth. NASA tested an early prototype of the Mars rover there because the terrain was the closest match available for the Red Planet. In 1822 prospectors discovered several large masses of the Imilac pallasite sitting in shallow impact pits. Nearby, they came across a compact strewnfield containing thousands of small pieces in close proximity. The surface of the Imilac meteorites showed considerable weathering, suggesting an old fall, and many olivine crystals had been sandblasted away by the desert wind, leaving behind small skeleton-like iron fragments. When cut and polished, the larger pieces reveal gorgeous green and gold angular crystals, unaffected by terrestrial weathering. Incredible! We have a few Imiliac part slices, please email to inquire.
NORTHWEST AFRICA 2932
Mesosiderite, Found in Morocco, 2005
Mesosiderites make up half of the stony-iron group — the rarest of the three main types of meteorites. Originally thought to have a similar origin story to their stony-iron “cousins,” the pallasites, they are now believed to be entirely unique. While pallasites frequently show a consistent distribution of their nickel-iron and silicate components, the interiors of mesosiderites are irregular. Northwest Africa (NWA) 2932 is a particularly excellent example of the brecciated and heterogeneous structure that is typical of mesosiderites. Note the large and highly prominent spherical nickel-iron inclusions, suspended in a mottled silicate and metal matrix. Similar nodules are seen in the Bondoc mesosiderite (found, 1956, Philippines), but those are stand-alone pieces as the silicate matrix that once enclosed them has, by and large, corroded away.
This exceptional polished end cut is a visually delightful specimen of an extremely rare meteorite that was found in Morocco in 2005.
NORTHWEST AFRICA 7657
Mesosiderite, Found in Morocco, 2012
This absolutely beautiful mesosiderite was discovered in 2012 in Morocco. Only a single stone was recovered, with a mass of 2.28 kilograms. After cut loss, that probably leaves not much more than 1.5 kg total in the world. We were lucky to acquire two full slices of this exquisite meteorite.
NORTHWEST AFRICA 10023
Pallasite, PMG-an, Found in Northwest Africa, 2014
This is a truly remarkable find from the northern deserts of Africa: an astoundingly vibrant pallasite with olivine colors ranging from blood tangerine all the way to lime green. There is a significantly high crystal density among the iron and they vary from small clusters to large, attention-seeking individuals.
In order to best display the interior, we have various slices that are polished on one face and etched on the other. Plus, each slice is cut thin in order to boost the transparency of the olivine crystals and allow one to create a brilliant, artistic show of color when presented with light, even if the light source may be quite dim. It is an unequivocally luxurious and bold pallasite.
NORTHWEST AFRICA 10882
Northwest Africa 10882, Mesosiderite A2, Purchased and classified by Steve Arnold in May 2016
A very rare mesosiderite A2 from a single mass. Saw cut shows a stony-iron breccia with silicate clasts up to ~1 cm, metal veins and nodules up to ~1 cm, however many domains are fine-grained mixtures of metal and silicate. Beautiful!
Pallasite, Found in Eastern Kenya, 2017
Few things create as much excitement in the meteorite world as the discovery of a new pallasite. The Sericho pallasite (sometimes called Habaswein), found quite recently in Kenya is just such a discovery. Numerous masses of varying size and widely varying degrees of weathering have been recovered. Our examples come directly from Kenya and the masses from which our slices are taken show minimal weathering. In fact, the exterior of our best masses show virtually no weathering at all, as indicated by the green crystals present in these specimens. Our slices have been beautifully prepared by an expert in pallasite cutting and polishing. Please note that they have not been coated with lacquer or other protective sprays! The faces show a natural high-gloss polish as a result of meticulous attention to detail in the lab.
Olivine crystals account for about 70% of the area of cut faces, and they show slight translucency with an attractive color palette ranging from light green to jade green, orange, and brown. With Imilac and Fukang selling at $35/gram and Esquel changing hands for as much as $70/gram, how do you feel about excellent, high quality full pallasite slices starting at only $6/gram and end cuts for less. A rare chance to acquire pallasite at an irresistible price.
Pallasite, Found in Russia, 1967
Pallasites with multi-colored crystals and transitional characteristics.
We are pleased to offer specimens of the olivine-rich Russian pallasite Seymchan. Originally classified as an iron (IIE), later Seymchan finds produced fabulous pallasitic material, some with an abundance of colorful olivine clusters. Seymchan is completely stable and it is rapidly disappearing from the marketplace. Some specimens are transitional in nature, in that they exhibit characteristics of both irons and stony-irons within the same slice.
SEYMCHAN FULL SLICES
Worldwide interest in meteorites continues to grow and olivine-rich Seymchan specimens are now extremely difficult to acquire. Raw, unprepared masses now sell for the same dollar per gram rate as fully polished slices did only five years ago. We are pleased to present these few, highly desirable full slices.
SEYMCHAN PART SLICES
SEYMCHAN IRON-RICH SLICES
Seymchan as an iron is an exceptionally attractive meteorite and features a spectacular etch pattern. We are pleased to offer iron siderite part and full slices.
Stony-irons are by far the rarest of the three main classes of meteorites; the others being irons and stones. Mesosiderites and pallasites make up the stony-irons and Vaca Muerta (spanish for “dead cow”) is a rare example of the mesosiderite type. First discovered in 1861 by prospectors looking for rare metals, the Vaca Muerta meteorite comes from a difficult-to-reach area in Chile’s vast Atacama Desert. The area has been extensively hunted since the 1960s and examples of this meteorite only rarely come to market.
