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 and a stand will also be included.

You will receive 1 Sikhote-Alin meteorite chosen for you at random.  This size of Sikhote-Alin is great for jewelry making and a variety other small projects.

These are great looking Russian Sikhote-Alin classified meteorites weighing 0.2-0.49 grams.  This Iron (IIAB) Coarsest Octahedrite classified meteorite was recovered in Russia after the fall of February 12, 1947.  So far approximately 23 tons of this material have been recovered.  These specimens are known as shrapnel specimens, ripped and torn edges reminiscent of bomb shrapnel. They broke due to atmospheric pressure and/or mid-air collisions, and possibly explosive fragmentation upon impact. These pieces are a good example of the shrapnel type Sikhote-Alin.

This is a 22.3 gram Grey Melt Rock from the Köfels Structure, Austria. It measures 38x22x21 mm.  The specific origin of kofelsite rocks is uncertain & debated. The rocks are found in a landslide deposit in western Austria. Researchers have suggested that the landslide was impact-triggered. The kofelsite samples in the landslide deposit thus may be impactites (fused rocks from the heat of impact). Some workers have suggested that the rocks are frictionites (fused rocks from landslide heating).

The Köfels landslide was a huge mountain rockslide (a Sturzstrom) that occurred in the Austrian Alps about 9800 years ago near the present day village of Köfels. Some of its features mystified geologists for quite some time. One hypothesis was that it had been caused by an asteroid impact — a Köfels impact event — but more recent research has rejected the idea. This didn't stop a pair of British engineers from publishing a book that claims that a) it was an asteroid impact, b) it inspired a lot of myths, and c) it was recorded on an ancient Sumerian clay tablet.

The reason for the original impact hypothesis was the presence of fused rock. At the time, the only processes known to be able to do this were either volcanism or meteor impacts. Later research found that it can be also produced by friction and similar fused rock has been found in other large rockslides.

This specimen displays very well even if not proven to be meteorite impact related.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a fantastic crusted 26.1 grams NWA (Northwest Africa) 869 L3-6 classified meteorite Individual found by Nomads in the Sahara Desert. The dimensions of the specimen are 46x24x16 mm.

NWA 869 classified meteorites can still be interesting and this one is for sure perfectly shaped to catch your attention. It displays a superb crust on most of its surface.  Most samples are individual meteorites but some fragments (mostly >1 kg) also occur. In most cases the fusion crust has been polished or ablated by wind erosion. Many samples are more severely affected and show faces with deep wind erosion features. Fracture faces, formed by ground collision, show a typical gray-green color and sometimes visible brecciation (light and/or dark clasts).

This is a rare and fantastic 5 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 30x21x9 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.

The distinctive "cat's eye" effect in this Chrysoberyl is caused by the reflection of light off parallel needle-like inclusions within the crystal. When the gem is cut en cabochon, a concentrated, bright band of light appears to move across the surface as the stone is rotated.
