The NWA 267 meteorite fragment offered here is in as found condition. It weighs 10.8 grams, with dimensions of 31x22x16 mm. The meteorite will come with two specimen description cards including a signed "The Mark Bostick Collection" card.
This meteorite was once a pile of weathered unclassified meteorite fragments brought to the 2000 Denver show by a Moroccan fossil dealer. These fragments, 73.9 kg. worth, where purchased by Canadian meteorite dealer Dean Bessey, who was told the following on the meteorites: "A nomad found an area with a lot of unusual strange stones near the Morocco/Algeria border. He brought one to a fossil dealer and asked: "I hear that you will pay money for stones like this". After shaking his head in disbelief at a positive response, the nomad gathered up all his camels, wives and children and brought them into the desert to search over his personal strewn field." Or at least that is how the story goes.
Many thousands of stones, 73.9 kilograms, were recovered, most of these fragments under 20 grams. Then 356 grams and a thin section of the meteorite was donated to the Vernadaky Institute of Geochemistry and Analytical Chemistry, part of the Russian Academy of Sciences, Moscow, where it was classified by M. Ivanova. This meteorite, an ordinary stone chondrite, H4 class has a Shock Rating of 2 and a Weathering Grade of 2-3 and the classification information was published in Meteoritical Bulletin 85.
While the stone did not get a heavy weathering grade, very few specimens show any crust. This meteorite is believed to have come from the Hebe class asteroids. I've included an informational photo of a NWA 267 Meteorite thin section which are used in earth geology, and in meteorites to identify the minerals in them. The photo shows a large imperfect elongated chondrule. Chondrules are unique features to meteorites. The chondrule shown is composed of mostly pyroxene and the bright colored minerals scattered throughout the thin section is mostly olivine.
One of the fun facts is that the NWA 267 was also the first meteorite ever minted onto a real legal tender coin. The National Bank of Liberia made 999 of these $10.00 Silver coins in 2004. The meteorite used in the coin, was supplied by Mark Bostick himself and his name and signature came on the certificate with the coin. The provided images of the coin shows a nomad on a camel on the obverse. A meteorite is falling through the star filled sky in the background. Reverse of coin has a seal of the Liberia Government and notes its value. We include 2 specimen cards but unfortunately the thin section and coin used in the ad are NOT included!
The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calite). It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions. It is metastable relative to calcite and often converts to calcite accompanying changes in the environment. It is nearly always a low-temperature, near surface mineral.

Quartz crystals are among the most abundant and well-known minerals on Earth. It belongs to the hexagonal crystal system, and typically forms six-sided prismatic crystals with a pointed termination. Its crystals can be colorless or exhibit a wide range of colors. The color variations are often due to the presence of impurities or trace elements during the crystal's formation. Quartz is transparent to translucent.
Phantom quartz is a variety of quartz, or "rock crystal", that forms over pre-existing crystals. The included crystal is visible due to some variation in composition making the boundary of the included crystal visible. Such crystals display the outlines of numerous smaller crystals, known as phantoms. Great crystal to acquire.

Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. Nice clear crystal with a small cloud passing by.

Labradorite is an unusual mineral. It can display a beautiful iridescent play of colors, caused by internal fractures in the mineral that reflect light back and forth, dispersing it into different colors. This effect, known as labradorescence, gives Labradorite its appeal and fame.

Here is a beautiful Sodalite sphere from Brazil. Sodalite is usually found in the massive form, rather than crystals. Its name is derived from its sodium content. This stone is frequently found with lapis lazuli, but contains little or no golden pyrite specks in it as lapis does. It may, however, contain patches or streaks of white calcite. Although some people think that sodalite resembles lapis in some ways, it is entirely different in chemical composition and has more of a navy blue coloring.
Would be a beautiful addition to any new or existing collection.
