Olivine Volcanic Bomb | Lava Coated Crystal | 293.8 gr | Mt Shadwell, Australia
Olivine Volcanic Bomb | Lava Coated Crystal | 293.8 gr | Mt Shadwell, Australia
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.

Moissanite has become a popular alternative to diamonds for jewelry. Moissanites have a similar appearance to diamonds and often look nearly identical to the untrained eye. They share the brilliance, sparkle, and fire that diamonds are known for, making them an attractive choice. With moissanite, it is possible to have a beautiful gemstone for a fraction of the price of a diamond. Moissanites are primarily produced in laboratories, offering a controlled and consistent quality. This aspect appeals to those who prefer gemstones with known origins and minimal environmental impact.
Originally discovered in a meteorite crater, Moissanite is well known worldwide as the world’s most brilliant gemstone, better than diamonds. Moissanite is incredibly rare in its natural form; however, lab created moissanite is identical to the original with hardness second only to diamond. Moissanites have a hardness of 9.25 on the Mohs scale, while diamonds are a 10. This makes moissanite suitable for everyday wear and less prone to scratching or damage.
This sparkling round cut pale yellow moissanite is a great choice for any jewelry project.

Impact Melt Rock | 9.8 grams | Dhala Impact Structure | 3rd Oldest Impact | India
$12.00 CAD
Unit price perImpact Melt Rock | 9.8 grams | Dhala Impact Structure | 3rd Oldest Impact | India
$12.00 CAD
Unit price perThis is a must have 9.8 gram Impact Melt Rock from the Dhala Impact Structure, India. It measures 40x26x5 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 items you'll ever own. 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 impactite 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 beautiful Impact melt rock comes from the 11 km-diameter highly eroded Dhala impact structure in India. The Dhala structure has an estimated age of about 2Ga (2,000 Ma), making it the third oldest terrestrial impact structure.
This gorgeous slice displays very well. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Olivine Volcanic Bomb | Lava Rock Crystal | 1.45 Kg, | Mt Shadwell, Australia
Olivine Volcanic Bomb | Lava Rock Crystal | 1.45 Kg, | Mt Shadwell, Australia
Volcanic bombs are large clots of volcanic lava rock 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 lava rocks contain olivine crystals, they are referred to as olivine volcanic bombs.
Mount Shadwell, a dormant volcano, was formed 25,000 years ago and is believed to have last erupted about 5,000 years ago. The town of Mortlake, which is situated at the foot of the volcano, is the self-proclaimed olivine capital of Australia. This is where large ejected rocks from Mt Shadwell, called volcanic bombs, are found.
This huge museum piece has been cut to show the green olivine crystals which are showcased beautifully against the surrounding black lava crust.
Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Gypsum var "Duckbill" Selenite Crystal | Fluorescent | 55.3 gr | Red River Floodway | Winnipeg, Manitoba Canada
$166.00 CAD
Unit price perGypsum var "Duckbill" Selenite Crystal | Fluorescent | 55.3 gr | Red River Floodway | Winnipeg, Manitoba Canada
$166.00 CAD
Unit price perWe have for you a large Duckbill style gypsum var Selenite from world famous Red River Floodway in Winnipeg, Manitoba Canada. This is a large floater gypsum crystal cluster that occurred in the Pleistocene Age in Lake Agassiz clay. The distribution of the gypsum covers a 20 kilometer wide area, but the Floodway is one of the few excavations in the very flat terrain deep enough to intersect the gypsum layer.
The Red River Floodway has become famous, not only for its engineering marvel but also for the extremely unusual selenite specimens that were discovered during excavations. The formation is due to two generations of growth with the first growth forming near-spherical rosettes of stout intergrown crystals and the second growth, that made them famous, grew large golden crystals with a unique twinning shape that resembled a duck’s bill. These “duckbill” selenites are famous the world over and have found nowhere else in the world to date and collecting is now carefully controlled. Specimens range from having a single crystal, to having many radiating from the rosette. Some rare examples have two rosettes conjoined in striking formations. This specimen is in excellent condition.
