These 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
C.   43x34x21 mm / 1.7x1.3x0.8 in  |  37 gr / 1.3 oz
D.  49x44x34 mm / 1.9x1.7x1.3 in  |  63.6 gr / 2.2 oz
E.  66x44x33 mm / 2.6x1.7x1.3 in  |  113.5 gr / 4.0 oz
F.  79x48x38 mm / 3.1x1.9x1.5 in  |  145.4gr / 5.1 oz

Any of these Olivine Bombs would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

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.

These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition.  This collector's specimen is unique, of great quality and ready for display.

Name: Goethite After Marcasite Pseudomorph
Specimen Size:  Miniature-Sized
Dimensions:  42x39x28 mm / 1.6x1.5x1.1 inches
Weight:  45.8 grams / 1.6 ounces
Origin: Found in White Desert, Farafra Oasis, Egypt

This 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.

Galena is a mineral composed of lead sulfide (PbS) with a cubic crystal structure. It has a silver-gray color with a metallic luster and the crystals have formed in the octahedron shape. Galena is historically significant as a source of lead, used in various applications, and is still important in modern industries. It is found globally, often associated with minerals like sphalerite and pyrite.

Cubic and crystallized Pyrite matrix with Marmatite crystal cluster.

Some of the more important Colorado localities for specimens of well-crystallized pyrite include mines at cli- max, Gilman, Leadville, Rico, Ouray, Telluride, Creede, Alicante, Alice, and State Bridge. Specimens from each of these localities often have distinctive crystal habits and mineral associations.  The Eagle mine is probably best known for its pyritohedral Pyrite specimens. This cluster is a good representative Eagle mine Pyrite showing typical striated pyritohedra with sharp, lustrous faces plus some Marmatite opaque black iron-rich crystals.

This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

Name: Pyrite with Marmatite Crystal Cluster
Specimen Size:   Cabinet-Sized
Dimensions:   65x44x42 mm / 2.6x1.7x1.6 inches

Here we have for you a large 51.8 grams superbly shaped Indochinite Tektite from Maoming City, Guangdong Province, China. Although not a meteorite, tektite is directly linked to them or their impacts, just consider its age of around 780,000 years old.

Tektite can still be interesting because of the persistent mystery has that resisted clear explanations of their creation for generations of geologists. Dimensions are 54x40x19 mm. 

This piece displays very well and is a very nice size showing multiple characteristics of its origin.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Amphibole 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.
