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 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.

Oolites in the Great Salt Lake, Utah, are tiny, sand-sized, spherical or ovoid grains (0.15–1.5 mm) formed by calcium carbonate precipitating in concentric layers around a nucleus—often brine shrimp fecal pellets or mineral fragments—in shallow, wave-agitated water. These light brown grains, commonly found on Antelope Island and Stansbury Island, are modern examples of carbonate sedimentation.

This geological specimen found around Stansbury Island and other parts of the Great Salt Lake is an interesting addition to any mineral collection.

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.

This specimen is remarkable for its relatively sharp and bladed marcasite crystal form.  It is in excellent condition.

The Gold Hill Wash Prospect, part of the Clifton-Gold Hill Mining District, is known for its rich mineral resources, including jarosite. This mineral is part of the larger group of minerals found in the area, which also includes limonite.

The Gold Hill Mine, operated by the Western Utah Copper Company in the early 20th century, was significant for its arsenic deposits, although it closed after World War I. The mine's portals and shafts have since been sealed by the state of Utah.

This specimen from the Gold Hill Mine is a matrix covered with minute jarosite crystals.  This specimen is an interesting addition to any mineral collection.

Name: Jarosite
Specimen Size:  Miniature-Sized
Dimensions:  53x49x33 mm / 2.1x1.9x1.3 inches
Weight:  64.91 Grams / 2.3 ounces
Origin: Mined in Gold Hill Mine, Gold Hill, Gold Hill Mining District (Clifton Mining District), Tooele County, Utah, USA

Pyromorphite (lead chloro-phosphate) was a common mineral of the oxidized zone of the Broken Hill orebody, and exceptional specimens of various crystal forms and colors were found. Some examples were yellow and some brown, while others were green. Their crystal habits varied from almost needle-like to thick barrels. This example illustrates one of those forms – barrel-shaped, six-sided, clove-brown crystals.

This hard to acquire specimen is in good condition.  A rare and really beautiful specimen. Would be a great addition to any new or existing collection.

Name: Pyromorphite 
Specimen Size:  Thumbnail-Sized
Dimensions:  22x9x8 mm / 0.9x0.3x0.3 inches
Weight: 5.74 Grams / 0.2 ounces

This is a fine dark green Epidote crystal from the tribal region bordering Afghanistan and Pakistan. This green crystal has luster and translucence. Comes in a protective specimen box.

Fine epidote specimens from the Pakistan-Afghanistan border region, particularly Gilgit-Baltistan (Shigar/Tormiq Valley) and Balochistan (Kharan/Zhob), are world-renowned for their intense green to dark brown color, high luster, and sharp crystal structure. These alpine-cleft specimens, often associated with white quartz, feature fan-like aggregates, bow-tie shapes, and excellent aesthetic, gemmy terminations. 

Product Name: Epidote Crystal
Specimen Size:  Thumbnail Sized
Dimensions:  14x9x9 mm / 0.5x0.3x0.3 inches
Weight:  1.96 Grams / 0.7 Ounces / 9.76ct
Origin: Mined in Gilgit District Pakistan

This is an attractive tiny spray of metallic stibnite crystals from the Xikuangshan Mine of China.

Cubanite is a rare copper-iron sulfide mineral prized by collectors for its distinctive brassy-yellow metallic luster and geometric crystal forms. This exceptional specimen originates from the now-closed Henderson No. 2 Mine in Chibougamau, Québec—a historically significant locality that produced some of the finest cubanite crystals in North America.

At 6.27 grams, this piece represents a substantial and well-formed example of the species. The mine's closure adds to the collectability and scarcity of material from this source. 

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

Name: Cubanite on Matrix
Specimen Size:  Thumbnail-Sized
Dimensions:  28x16x8 mm / 1.1x0.6x0.3 inches
Weight: 6.27 Grams / 0.2 oz
Origin: Mined in Henderson No. 2 mine, Chibougamou, Québec, Canada

This amazing specimen of Grossular Garnet was collected in the now closed Jeffery Mine in Asbestos, Québec, Canada. This is an extremely elegant and classic cinnamon colored garnet from this locale. 

The Jeffrey Mine is well-regarded among mineral collectors for its grossular garnet specimens, particularly the rich orange (“hessonite”) crystals it produced during its active years. The mine’s grossular garnets are often described as some of the most distinctive and desirable in the world because of their strong, honey-orange to peach color, good transparency, sharp crystal form, and glassy luster — qualities that make them stand out compared to grossular from many other localities.

Today the mine is closed and flooded, so material comes from historic finds and old stock, adding to both rarity and appeal.

This beautiful specimen is in very good condition and will come protected in a Perky Box . A great addition to any collection!

Orange spessartine garnets from California are highly regarded for their intense "mandarin" orange color and are often found in matrix, particularly in the pegmatites of Southern California, including areas near Kern County. While the most famous, high-quality, gemmy spessartine crystals in matrix, accompanied by schorl and quartz, are famously associated with the Little Three Mine in nearby Ramona (San Diego County), similar pegmatite occurrences in the region, including Kern County, produce desirable collector specimens. 

Spessartine garnet is considered a "high vibration" stone and is often associated with creativity. The specimens from this region are known for being 100% natural and untreated.
