An olivine volcanic bomb is a type of volcanic rock that contains olivine crystals and has been ejected during a volcanic eruption. Olivine is a mineral that is commonly found in the Earth's mantle and is one of the first minerals to crystallize as magma cools.

Volcanic bombs are large clots of lava that are ejected from a volcano during an explosive eruption. They can vary in size, and their shapes are often streamlined due to their molten nature as they are thrown through the air. When these volcanic bombs contain olivine crystals, they are referred to as olivine volcanic bombs.

This piece has been cut to showcase the beautiful green olivine crystals.  It would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.  Stand is not included.

This is a nice end cut of the Northwest Africa 978 meteorite. This is another of the great and rare meteorites from the Sahara. It is classified as a Stone, Chondrite Rumurutiite, (R3.8). This meteorite was found in 2001 in many fragments and small individuals, very fresh but sandblasted for a low TKW of 722 grams. The Shock stage is registered at 3 and the Weathering grade at 2.

It is one of the rarest meteorite types with only 9 Rumuruti 3.8 type meteorites known,  most being found in Antarctica. This unique group of chondrites has basically no FeNi-metal in comparison to other chondrite groups. The R chondrites also have the highest 17O value of any other solar system material. This piece weighs 3.03 grams an measures  20x14x6mm. Note the flat edge of this piece is crusted, it is not a cut surface.

This hard to acquire piece displays very well with its diamond lap finish and this high quality specimen would make an amazing addition to any new or existing collection. Comes with a Canagem Collection specimen cards.

This Microcline feldspar cluster from Nevada is a quality specimen that would be a beautiful addition to any new or existing rock collection.

Microcline is one of the most common feldspar minerals. It can be colorless, white, cream to pale yellow, salmon pink to red, or bright green to blue-green. Microcline forms short prismatic or tabular crystals that are often of considerable size: single crystals can weigh several tons and reach yards in length.

Crystals are often multiply twinned, with two sets of fine lines at right angles to each other. This gives a plaid effect that is unique to microcline among the feldspars.

This is a superb looking Stony-iron or Mesosiderite Vaca Muerta (Dead Cow) classified meteorite weighing 5.2 grams. Its dimensions are 26x12x9 mm.

This classified meteorite was found in 1861 in the driest desert of the world called the Atacama, in Chile. Mesosiderites are formed on the surface of a parent body as a result of impacts with another body. The impact mixed broken fragments of surface eucrites with iron and olivine from deep within the body. Eucrites are believed to have come from the asteroid Vesta. Analysis has shown, however, that the Vaca Muerta eucrite inclusions are not consistent with other eucrites and possibly originated on a different parent body. Although most have a weathered exterior, they also have lots of metal inside and can be prepared and cut to show this.

This piece displays extremely well and would be a beautiful addition to any new or existing collection. Comes with a BA-Meteorites (Dr. Bernhard Brinker, Mineralogist and Martin Altmann, IMCA #3825) and a Canagem Collection specimen card.

Here we have for you a superb end cut of the famous Vaca Muerta (Dead Cow) classified meteorite weighing 3.12 grams. Its dimensions are 20x19x5 mm.

This classified meteorite was found in 1861 in the driest desert of the world called the Atacama, in Chile. Mesosiderites are formed on the surface of a parent body as a result of impacts with another body. The impact mixed broken fragments of surface eucrites with iron and olivine from deep within the body. Eucrites are believed to have come from the asteroid Vesta.

Analysis has shown, however, that the Vaca Muerta eucrite inclusions are not consistent with other eucrites and possibly originated on a different parent body.  This particular specimen is a cut of a eucrite nodule with none of the typical mesosiderite of Vaca Muerta.

This rare specimen displays extremely well and would be a beautiful addition to any new or existing collection.  Comes with an ELKK Meteorites and a Canagem® specimen card.

This beautiful Apophyllite specimen is of significant size and will include the stand seen in the photos.

Apophyllite is a mineral belonging to the phyllosilicate group. It is known for its distinctive crystal formations, often occurring in clusters with a unique beauty.  Apophyllite crystals are usually colorless or white, allowing them to be transparent or translucent. Although, some specimens may exhibit a greenish, yellowish, or pinkish tint due to the presence of impurities. 

Apophyllite often forms as prismatic crystals with a square or rectangular cross-section.  It frequently occurs in distinctive pyramid-like structures, and its crystals can be large and well-formed. Apophyllite is found in various locations around the world. Notable occurrences include India, Brazil, Mexico, Germany, and the United States.

Apophyllite is believed to have a calming effect, and to effectively reduce stress, releasing mental blockages and negative thought patterns. Apophyllite is also said to release suppressed emotion, to overcome anxiety, worries and fears. It calms apprehensions and allows uncertainty to be tolerated.

The NWA 267 meteorite fragment offered here is in as found condition.  It weighs 16.6 grams, with dimensions of 28x27x22mm.  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!
