Crystals & Minerals

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 beautiful slice is completely surrounded by a lava crust and has been polished on both sides. 

Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This beautiful cluster combines tetrahedrite, cubic and crystallized pyrite matrix and tiny terminated quartz crystals. 

Tetrahedrite crystals are fascinating minerals known for their distinctive tetrahedral shape and shiny, metallic luster.  It typically forms in well-defined tetrahedral crystals, which can be grouped in clusters.  The color range includes shades of metallic gray, black, and sometimes reddish hues due to the presence of copper and other trace elements. Tetrahedrite is commonly found in hydrothermal veins and is often associated with other minerals such as quartz, galena, and sphalerite.

Tetrahedrite is believed to promote emotional healing and provide a protective shield against negativity. It is thought to enhance creativity and clarity, helping individuals connect with their inner selves.

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

This specimen features beautiful brown Phlogopite crystals on matrix, from the Earl's Farm, Wilberforce, Ontario, Canada. 

Phlogopite is a fascinating mineral belonging to the mica group, recognized for its distinctive layered structure and glossy appearance. Its color typically ranges from light brown to dark brown, and it can sometimes display a golden hue. Phlogopite is notable for its excellent cleavage, allowing it to be split into thin, flexible sheets, much like other mica varieties.

Phlogopite is typically found in metamorphic rocks, especially in areas where there has been significant heat and pressure, such as around granite intrusions. It is commonly located in places like Madagascar, Russia, and parts of North America, often forming alongside other minerals, such as biotite and garnet.

Phlogopite is believed to promote inner strength and self-confidence. It is often associated with grounding energy, helping individuals remain centered and calm amid chaos.

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.

This is an attractive specimen of calcite crystals from the Wessels Mine, Kuruman, South Africa.  The entire top surface of the specimen is covered with many sharp well formed calcite crystals. Some are a frosted snow white ball shape which sit amongst a sharper sparkly druzy calcite. It is in excellent condition.

Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble.

Iceland spar, formerly called Iceland crystal (Icelandic: silfurberg [ˈsɪlvʏrˌpɛrk], lit. 'silver-rock') and also called optical calcite, is a transparent variety of calcite, or crystallized calcium carbonate, originally brought from Iceland, and used in demonstrating the polarization of light.  

The most common crystal structure of Iceland spar is rhombohedral, but other structures, such as scalenohedral or prismatic, can form depending on formation conditions. Iceland spar is primarily found in Iceland but can occur in different parts of the world with suitable geological conditions such as China.

This is a natural cluster formation of large calcite crystals with hematite inclusions. This piece has some white color to translucent crystals with areas of orange/red coloring from hematite inclusions, with sharp tabular crystal formations. There are some nicks and imperfections on a few crystals but would still shine in the proper setup.  They don't take away from how interesting this piece is.  Would be a nice addition to any new or existing collection.

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.

This specimen of Vesuvianite was collected in the now closed Jeffery Mine, Asbestos, Québec, Canada. The specimen is made up of a combination of green and mauve vesuvianite crystals also named violet manganoan vesuvianite. It is in good condition. A great addition to any collection!

Vesuvianite was first discovered on Mount Vesuvius in Italy in the 18th century, hence its name. It typically occurs as a green, brown, yellow, or blue-green crystal, and is often found in metamorphic and igneous rocks. The alternate name, Idocrase, is from the Greek eidos “form”, and krasis “mixture”, because Vesuvianite often appears to combine the crystal forms of other minerals. It is used as a gemstone.
