This is a must have 27.4 gram Impact Melt Rock from the Stac Fada Member Impact Structure, NW Scotland. It measures 66x37x5 mm. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection items you'll ever own. Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite.
The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc.
This beautiful Impact melt rock comes from the Stac Fada impact structure in Scotland. The structure has an estimated age of about 1.2Ga (1,200 Ma). The Stac Fada Member of the Precambrian Stoer Group in Scotland has previously been described as volcanic in origin. However, shocked quartz and biotite provide evidence for high-pressure shock metamorphism, while chromium isotope values and elevated abundances of platinum group metals and siderophile elements indicate addition of meteoritic material. Thus, the unit is reinterpreted as having an impact origin.
This gorgeous slice displays very well. Would be a beautiful addition to any new or existing collection. Comes with two a Canagem Collection specimen card.
The NWA 267 meteorite fragment offered here is in as found condition. It weighs 6.03 grams, with dimensions of 24x19x14mm. 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!
Orange spessartine garnets from California are highly regarded for their intense "mandarin" orange color and are often found in matrix, particularly in the pegmatites of Southern California, including areas near Kern County. While the most famous, high-quality, gemmy spessartine crystals in matrix, accompanied by schorl and quartz, are famously associated with the Little Three Mine in nearby Ramona (San Diego County), similar pegmatite occurrences in the region, including Kern County, produce desirable collector specimens.
Spessartine garnet is considered a "high vibration" stone and is often associated with creativity. The specimens from this region are known for being 100% natural and untreated.

This is a superb looking part slice of Sahara Desert NWA 2224 meteorite. Although still considered unclassified, this meteorite was given the provisional class of CV3 for Carbonaceous.
This is a great specimen with many multicolored chondrules and CAIs. It's a Dean Bessey meteorite but unfortunately many of his finds were never fully submitted for analysis. It is a shame for this particular specimen, as it is just spectacular.
This piece displays extremely well with its professionally finished cut face and comes protected in a gem jar. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
