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 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!

This is a large Hornblende crystal from Tory Hill, Ontario.  The specimen has all crystal faces and terminations. It is a lustrous black color and in very good condition. There is also minor apatite on some of the surfaces. The specimen is in excellent condition.

This locality dates to the late nineteenth century and fine specimens from here are hard to obtain.

This is a superb looking slice of a Sahara Desert NWA 091 classified meteorite weighing 11.53 grams. Its dimensions are 33x26x4mm. 

It is a nice dark gray color and is full of small holes (the small black specks in the pictures). It is very similar to Kimble County except a bit darker. The single piece was found in the desert in 2000 and has a total mass of only 370 grams and was classified as an L6 by UCLA. It is shock level 4 (very high) and weathering grade W2 (Low). It is highly vesiculated from a shock event.

This piece displays extremely well with its professionally finished cut face and is also a very nice size. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

A pseudomorph occurs when one mineral replaces another but retains the original mineral's crystal structure. In the case of turquoise after apatite pseudomorph, turquoise  replaces apatite, but it still retains apatite's crystal shape.

This process leads to a visually fascinating specimen where the exterior shape looks like apatite crystals, but the composition and color are distinctly turquoise, often with the bright blue or green shades typical of turquoise.

This is a stunning thumbnail sized specimen of Quartz and Hydroxylherderite.  There are many fully terminated quartz point, some of them surrounding the Hydroxylherderite.  Some crystallized pyrite is visible on the bottom of the cluster.

Quartz crystals are among the most abundant and well-known minerals on Earth. Quartz belongs to the hexagonal crystal system. It 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. 

Hydroxylherderite is a relatively rare mineral that belongs to the phosphate mineral group. It is comes in a variety of colours: Colourless, gray, brown, pale yellow, greenish white, light blue, and purple.  Notable occurrences of Hydroxylherderite include Brazil, Afghanistan, and the United States.

This specimen would be a beautiful addition to any new or existing collection.
