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.

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.

Stilbite is a zeolite mineral appreciated for its delicate crystal formations and pastel hues, ranging from colorless to white, yellow, pink, and peach.  It forms distinctive tabular crystals with a bowtie or butterfly shape and exhibits a vitreous to pearly luster. Commonly found in cavities in volcanic rocks, stilbite is associated with other zeolite minerals. It is valued for its aesthetic appeal and is believed by some to have calming energy, supporting spiritual growth and emotional healing.

This is a great looking Russian Sikhote-Alin classified meteorite weighing 26.2 grams. Its dimensions are 34x22x11 mm. This Iron (IIAB) Coarsest Octahedrite classified meteorite was recovered in Russia after the fall of February 12, 1947.

So far approximately 23 tons of this material have been recovered. This piece displays extremely well and is a very desirable size. These specimens are known as shrapnel specimens, ripped and torn edges reminiscent of bomb shrapnel. They broke due to atmospheric pressure and/or mid-air collisions, and possibly explosive fragmentation upon impact. These pieces are a good example of the shrapnel type Sikhote-Alin.

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

Sharp lustrous metallic crystals makes this top specimen of Skutterudite most beautiful and unique.  Some pearly white Calcite is intergrown between crystals.  Although most Skutterudite are uninteresting in form, several localities have produced sharp, lustrous crystals that are striking in aesthetics like this one.

The Bou Azer District, Morocco, produces the best examples of Skutterudite, in large, lustrous crystals, often in a cuboctadral shape.  Skutterudite may partially alter to pink Erythrite. Skutterudite is named after its type locality of Skutterud, Norway. 

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

This is a Selenite sphere from Morocco. The sphere comes from a selenite mass of Satin Spar, and is partially clear (the rest is translucent), with a lovely Chatoyancy.

Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals and even trapped bubbles of air and water.

Gypsum has several variety names that are widely used in the mineral trade. "Selenite" is the colorless and transparent variety that shows a pearl like luster and has been described as having a moon like glow. The word selenite comes from the Greek for Moon and means moon rock. Another variety is a compact fibrous aggregate called "satin spar" . This variety has a very satin like look that gives a play of light up and down the fibrous crystals. A fine grained massive material is called "alabaster" and is an ornamental stone used in fine carvings for centuries, even eons.

Selenite is said to be a calming stone that instills deep peace and is excellent for meditation.  Selenite has an ethereal quality and is said to inhabit the place between light and matter.  Although an ancient stone, it is still one of the most powerful crystals.

It is said that Selenite can be used to form a protective grid around a house, creating a safe and quiet space that does not allow outside influences in.  A large piece of Selenite placed in the house ensures a peaceful atmosphere.

Would be a beautiful addition to any new or existing collection.

This is a rare and fantastic 31 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 45x41x25 mm. 

Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites​. Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya.

This beautiful cluster of tetrahedrite with calcite, small terminated quartz crystals and small, but brilliant, crystallized pyrite. 

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.
