This is a rare and fantastic 41.8 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 44x38x24 mm.  Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites.

Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya.  Characterized by its yellow to greenish-yellow color, it lacks the aerodynamic shapes of tektites and often appears as irregularly shaped pieces. It is almost pure silica (around 98%) with very few impurities. Throughout history, it has been regarded as a mystical and powerful material, sometimes used in talismans and amulets.

This piece displays extremely well and is a quality translucent specimen. It has an aesthetic shape with a beautiful wind eroded body from the years spent in the Desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

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.

Oolites in the Great Salt Lake, Utah, are tiny, sand-sized, spherical or ovoid grains (0.15–1.5 mm) formed by calcium carbonate precipitating in concentric layers around a nucleus—often brine shrimp fecal pellets or mineral fragments—in shallow, wave-agitated water. These light brown grains, commonly found on Antelope Island and Stansbury Island, are modern examples of carbonate sedimentation.

This geological specimen found around Stansbury Island and other parts of the Great Salt Lake is an interesting addition to any mineral collection.

This is a must have 3-gram Impact Fallback Breccia from the Wanapitei Impact Crater at Wanapitei Lake, near Sudbury in Ontario Canada. Its dimensions are 37x13x5 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 pieces you'll ever own. 

Wanapitei Lake, located northeast of Sudbury, Ontario, is a 37-million-year-old meteorite impact crater, with its impact origin confirmed by the presence of suevite found in glacial drift surrounding the lake. Suevite is a type of breccia containing dark, vesicular glass formed under high-pressure shock metamorphism

Identified in the 1970s, the suevite at Wanapitei is a crumbly, shock-metamorphosed rock that often contains coesite, a high-pressure mineral diagnostic of impact structures.  The impact occurred during the Late Eocene epoch, roughly 37 million years ago. The crater is estimated to be 7 to 8.6 km in diameter, with the lake sitting on the edge of the much older and larger Sudbury Basin. The suevite appears very similar in composition to that found in the Ries crater in Germany, often containing bits of dark glass and partially melted clasts.

Note that this is not a meteorite but a slice of Earth rock, altered by a meteorite impact. A very, very large meteorite.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card. 

This is a nice looking individual fragment of a Sahara Desert NWA unclassified meteorite. It weighs 65 grams and measures 39x38x32 mm. This never classified Northwest Africa stone was found in the Sahara desert around 2000.

It's a good quality NWA meteorite individual fragment. 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.

This is a rare and fantastic 2.4 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 19x14x11 mm.  Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites.

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 and bladed marcasite crystal form.  It is in excellent condition.

This is a rare and fantastic 59 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 62x47x27 mm.  Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering.

Most cassiterite crystals have opaque, dark colors, usually black or brown. Lighter-colored, facetable crystals are much rarer and usually occur in small fragments. With a dispersion or fire almost twice that of diamond as well as vitreous to adamantine luster, transparency, and a hardness of 6-7, faceted cassiterites would make good jewelry stones. Cassiterite is a durable gemstone with tremendous dispersive fire, especially visible in properly cut pale-colored stones.  Unfortunately, facetable rough is very scarce. 

However, the combination of rarity and little consumer awareness means you’ll more likely find these for sale as collector’s specimens.
