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.

This specimen is remarkable for its relatively sharp marcasite crystal form.  It is in excellent condition.  

Name: Goethite After Marcasite Pseudomorph
Specimen Size:  Miniature-Sized Specimen

This is lot of small tumbled individual NWA unclassified meteorites from the Sahara Desert.  Because they have been tumbled, you can clearly see the metal within the specimens. The total weight of the lot is 8 grams and the meteorites range in size from 9 to 17 mm.  This never classified North West Africa stone was found in the Sahara desert around 2000.

These small individual specimens are great as teaching tools in the home or in the classroom, or as gifts.   They can also be used for science projects and other types craft displays. Comes with a Canagem Collection specimen card.

This is a superb looking part end cut of the Shişr or Shi 010 meteorite, weighing 4.4 grams. Its dimensions are  29x24x7 mm. This L5 classified meteorite was part of the 16 stones found in the Shişr Desert of Oman by Russian meteorite hunters in 2001 with a total mass of 17.6 Kg. The shock stage of 3 and weathering grade of 3 is recorded for these pieces.  This meteorite is likely paired with Shişr 008, an L5 that weighed 244 grams.

This piece shows a nice polished face and is a desirable size perfect to show in class or at a science show.  This specimen would be a beautiful addition to any new or existing collection.  Will come with a Canagem specimen card.

This is an outstanding Impact Melt Glass specimen or bomb weighing 7.89 grams.  Its dimensions are 28x28x22 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.

Large crystal of Fluor-Richterite and ivory colored calcite.  Fluor-Richterite is a rare mineral found only in the Wilberforce area in a skarn formation from the intrusion of magma into limestone with various impurities.  Would be a nice addition to any new or existing collection.

Name: Fluor-Richterite with Calcite Crystal
Specimen Size:  Miniature-Sized
Dimensions: 35x24x16 mm / 1.4x0.9x0.6 inches
Weight:  14.1 grams / 0.5 ounces
Origin: Mined in Wilberforce, Ontario, Canada

Aegirine, also known as acmite, is a rare and stunning black mineral. It is found in many locations around the world, but its most prized specimens come from Mount Malosa in Malawi, where it is often found in association with Microcline.

Aegirine is usually black, greenish-black, or brownish-black in color and has a glassy or vitreous luster. It has a hardness of 6 to 6.5 on the Mohs scale, which means it is relatively hard and durable. Aegirine is also known for its straight, needle-like crystals that can grow up to several centimeters in length.  

Microcline, a member of the feldspar mineral family, is known for its beautiful color variations and distinctive twinning patterns. When paired with Aegirine, the result is a striking and eye-catching contrast of colors.

Aegirine is believed to have properties associated with protection, energy balancing, and spiritual growth. Microcline, being a feldspar, is often linked to creativity and intuition. The combination of these minerals is thought to enhance their individual metaphysical properties.

This Aegirine on Microcline crystal is the perfect combination for those looking for a unique and beautiful addition to their mineral collection!

Name: Aegirine on Microcline crystal  
Specimen Size: Miniature-Sized   
Dimensions:  45x15x16 mm / 1.8x0.5x0.6 inches  
Weight: 6.97 grams / 0.2 ounces  
Origin:  Mount Malosa, Zomba, Malawi

This is a superb individual Tsarev meteorite weighing 60.4 grams. Its dimensions are 47x40x20 mm. Twenty-eight specimens of this L5 classified meteorite were found in fields.  The largest mass weighs 284 kg, the smallest 761 gr with a total weight of 1.23 Tons. The greatest distance between the find sites was 6.0 km.

In 1968, amidst a global surge in conflicts, a remarkable discovery was made in a small village in Volgograd Oblast. This region, known as the primary site of the Battle of Stalingrad—one of the largest and bloodiest battles in history—yielded an extraordinary find in the quiet fields near the rural village of Tsarev.

The Tsarev meteorite, named after the Russian word for czar, is a stone meteorite responsible for one of the largest meteorite showers in Russian history. This meteorite shower occurred on December 6, 1922, but the stones were not discovered until 1968 and only recognized in 1979. The Tsarev meteorite's mineral composition matches that of ordinary chondrites, including olivine, orthopyroxene, clinopyroxene, maskelynite, calcium phosphates, nickel-iron, troilite, chromite, ilmenite, and rutile.

Academic analysis of the Tsarev meteorite reveals significant features: large grains of nickel-iron, light grey areas with well-preserved chondritic texture, and dark areas containing a matrix with olivine grains and remnants of chondrules. 

This specimen would be a beautiful addition to any new or existing collection.  Will come with a Canagem specimen card.
