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.

This is an outstanding specimen Impact Melt Glass, or "Flädle" glass, from the Lake Mien crater, 12 km (7.5 mi) southwest of the town of Tingsryd, Sweden.   It weighs 16.5 grams and measures 41x35x7 mm.  Although not a meteorite, impactites are directly linked to them and their impacts.

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 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 eroded crater is marked by a 5.5-km (3.4-mi) diameter circular lake named Lake Mien. The original crater rim is estimated to have been about 9 km in diameter before erosion. Its age is estimated to be 121.0 ± 2.3 million years (Early Cretaceous).  This Suevitic breccia with clastic matrix and melt inclusions (black) and crystalline rock clasts (gray to white) is amazingly light considering its mass.   It has a unique hollow sound when you tap it.

Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is an outstanding Impact Melt Glass specimen or bomb weighing 11.6 grams.  Its dimensions are 35x27x23 mm.  Although not a meteorite, impactites are directly linked to them and their impacts.

This Henbury glass, or more specifically vesicular impactite, was found in the Northern Territory of Australia. Thirteen craters were found 8 miles southwest of the town of Henbury, the largest of which was 720 x 360 feet.  Henbury impactite was formed by a meteorite impact that occurred around 4,700 years ago. The meteorite is believed to have exploded upon entering the Earth's atmosphere, creating multiple craters which produced the impact glass.

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 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 piece displays extremely well.  It is amazingly light considering its mass.  It has a unique hollow sound when you tap it.  This Australian find is very well shaped and preserved. These pieces are becoming more difficult to acquire so this is a good time to get a fine specimen.  Would be a beautiful addition to any new or existing collection.  Will come with a Canagem specimen card.

Orpiment is known for its strikingly bright yellow color, though it can also be bright orange or lustrous brown. The name Orpiment is derived from the Latin Auripigmentum, meaning gold pigment, in reference to its color and historical use as a golden-yellow pigment. Orpiment is often associated with bright red Realgar, and may form in strikingly colored and unique mineral combinations.

Orpiment is a photosensitive mineral and will eventually dull and develop a white powdery film upon prolonged exposure to light. Due to the instability of Orpiment, specimens should be stored enclosed and covered to prevent their exposure to light. Occasional exposure to look at a specimen will not cause damage; only prolonged or repeated exposure will cause deterioration.

Orpiment contains a significant amount of poisonous arsenic, and is itself somewhat toxic. Washing hands is recommended after handling Orpiment specimens, especially if powdery.

This is a quality specimen that would be a beautiful addition to any new or existing rock collection.

Here we have for you a nice looking end cut of a Sahara Desert NWA unclassified meteorite weighing 12 grams. Its dimensions are 27x27x8mm. This never classified North West Africa stone was found in the Sahara desert around 2000.

It's a good quality individual cut fragment NWA meteorite specimen. Some weathering shows the meteorite's time spent aging in the desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another.  The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.

The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.

These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition.  This collector's specimen is unique, of great quality and ready for display.
