Unit price perOlivine Volcanic Bombs | Uncut Lava Coated Crystal | Mortlake, Victoria, Australia
From $8.39 CAD
Unit price perThese are whole, uncut lava coated volcanic bombs from Mortlake, Victoria, Australia . The lava crust on these pieces is complete, they can be showcased as is or cut to show the interior. The lava is most likely covering green olivine crystals.
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.
The dimensions and weight of each of these olivine bombs are as follows:
A. 32x25x17 mm / 1.3x1.0x0.7 in | 14.2 gr / 0.5 oz
B. 37x25x22 mm / 1.5x1.0x0.9 in | 23 gr / 0.8 oz

Impactite Vesicular Breccia Suevite | 76.5 Grams | La Valette, France | Rochechouart Structure
$51.26 CAD
Unit price perImpactite Vesicular Breccia Suevite | 76.5 Grams | La Valette, France | Rochechouart Structure
$51.26 CAD
Unit price perThis is a must have 76.5 gram Impact Vesicular Breccia also referred to as Suevite coming from the famous Rochechouart impact structure in South Western France, near the village of La Valette. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection item 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 impactite was formed 186 million years ago. This deformed rock fragments and partly molten are imbedded in a melt matrix showing typical flow structures from former melt.
This gorgeous end piece displays very well with a mass of 92.3 x 71.3 x 9.8 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Amphibole on Matrix | 63.44 gr | Vlčí Hora, Czech Republic
$51.97 CAD
Unit price perAmphibole on Matrix | 63.44 gr | Vlčí Hora, Czech Republic
$51.97 CAD
Unit price perAmphibole is a group of dark-colored, complex silicate minerals that form in a variety of geological settings. The amphibole group includes several mineral species, such as hornblende, tremolite, actinolite, anthophyllite, and others. Each variety has its own unique chemical composition and physical properties.
Amphibole minerals can exhibit a range of colors, including dark green, black, brown, and even colorless. They often have a prismatic crystal habit, forming elongated crystals with distinct cleavage angles. They are commonly found in igneous and metamorphic rocks. They crystallize in magma and can also form during metamorphism when pre-existing rocks are subjected to high pressure and temperature.
This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

Unit price perAdamite Crystals on Matrix | 77.1 grams | Mina Ojuela, Mapimi, Durango, Mexico
$51.97 CAD
Unit price perhis is an Adamite Crystals on Matrix mined in Mina Ojuela, Mapimi, Durango, Mexico. Adamite typically occur as small, brightly colored, prismatic or blocky crystals, or as crusts or aggregates. It is commonly found in association with other minerals such as limonite, calcite, and smithsonite. Adamite colors include green, yellow, white, and reddish-brown. The green color of adamite is caused by the presence of traces of copper in its crystal structure. One of the unique features of adamite is its strong fluorescence under ultraviolet (UV) light. It can exhibit vibrant green or yellow fluorescence.
Adamite was first discovered in 1866 in the Ojuela Mine in Durango, Mexico. It was named after French mineralogist Gilbert-Joseph Adam (1795-1881), who studied the mineralogy of the mine.
Adamite is associated with joy, creativity, and the balancing of energies. Some believe it can enhance one's ability to express themselves and promote a positive outlook. It is highly valued by collectors for its bright colors and distinctive crystal habits and would be a great addition to any new or existing collection.

Impact Melt Breccia | 50.7 Grams | Sääksjärvi Crater, Finland
$52.70 CAD
Unit price perImpact Melt Breccia | 50.7 Grams | Sääksjärvi Crater, Finland
$52.70 CAD
Unit price perThis is a great 50.7 gram Impact Melt Breccia from the Sääksjärvi crater in Finland. It is amazingly light considering its mass of 54x42x25 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 item 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.
Sääksjärvi is a lake in Kokemäki, Satakunta, western Finland, east of the town of Pori. The lake is notable because it overlies an impact crater. The crater is 5 kilometres (3 mi) in diameter and is completely buried under the lake and is not visible at the surface. The age of the impact structure is estimated to be about 543 ± 12 Ma (million years ago), at the boundary between the Ediacaran and Cambrian periods. There are impactite rocks in the southwestern region from the crater confirming its extraterrestrial origin. At the time of its discovery, only one impact crater (Lappajärvi) was known in Finland.
Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
