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 knows 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!

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 and it has been prepared as colorful slices which are described as Bondoc silicates.
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 United States, 1882
The Brenham meteorite was first discovered during the 1880s in 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 locatility 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.
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. We are offering both polished and etched slices for you to choose from. The absolute finest display piece.
Pallasite, Found in Argentina, 1951
Natural, elegant and simple… yet stunning. Highly translucent crystals in a sea of nickel-iron. Captivating!
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!
NORTHWEST AFRICA 7045
This is something you don’t often see! A pallasite from Northwest Africa. Although somewhat weathered, they still contain plenty of iron and have significant density. The polished faces show lovely markings and are reminiscent of the Huckitta pallasite. We only have a few of these pieces and this unusual desert find is a must for pallasite collectors.
NORTHWEST AFRICA 7154
Mesosiderite, Found in Northwest Africa
This stunning mesosiderite was discovered in Morocco. Only 1 small mass was recovered, with a total weight of 148 grams. We were fortunate to acquire two full slices of this striking new meteorite. The name is provisional, as it pending classification.
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 10882
Mesosiderite A2, Found in Northwest Africa, 2016
Rare A2 classification! Only three other meteorites total in this class. Mesosiderites make up the stony-iron group, along with their not-really-related cousins, the pallasites. With their dark silicate matrix and large, shiny metallic inclusions, polished mesosiderites look more like the actual night sky than any other meteorite class. Very similar in appearance to famed Vaca Muerta (and possibly from the same parent body), NWA 10882 is peppered with bright metal nodules and has a total known weight of only about 4 kilograms. Mesosiderites may have formed when two different types of asteroids collided: one injecting molten metal into the largely silicate body of its target, forming a nickel-iron and silicate cosmic sandwich! Bon appetite!
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 its current price is far below that of similar pallasites. 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 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.
SEYMCHAN PREMIUM SLICES
Natural, elegant and simple. These museum worthy meteorites — with an incredible backstory — make beautiful statement pieces.
