The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite). It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions. It is metastable relative to calcite and often converts to calcite accompanying changes in the environment. It is nearly always a low-temperature, near surface mineral.

Here we have for you a great looking individual cut fragment of a Sahara Desert NWA unclassified meteorite weighing 309.6 grams. Its dimensions are 86x58x52mm. This never classified North West Africa stone was found in the Sahara desert around 2000.

It's a good quality individual fragment NWA meteorite specimen. Some weathering shows the meteorite's time spent aging in the desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Herkimer Diamonds are beautiful double-terminated quartz crystals which are found mainly in Herkimer County, New York. Incredibly, these phenomenal gemstones are believed to be close to five hundred million years old. The crystals are magnificent works of nature found in the rock, appearing to have been precision cut by man and having a diamond-like geometrical shape; thus, the name Herkimer Diamond.  Many collectors believe the Herkimer Diamond should rival a true diamond and their reasoning for this is that a true diamond found in the rough is exactly that, a rough appearing glass-like stone. The diamond must be painstakingly cut by man to give it smooth faces and a geometrical shape.

In fact, Herkimer Diamonds are not diamonds.  A true diamond is one of the hardest elements known to man, scoring a ten on a one to ten hardness scale.  Herkimer Diamonds are harder than all quartz crystals. They fall at about 7.5 on the Mohs hardness scale, giving the real diamond a close race.  For comparison, many man-made steels barely score a seven on the hardness scale.

This stone is said to energize, enliven, and promote creativity.  The smaller, exceptionally clear stones are said to be powerful attunement crystals, stimulating psychic abilities, such as clairvoyance, spiritual vision, and telepathy.  It is also said that Herkimer attunes people and links them together when they have to be parted if each person has a stone.

Unique and in great condition ready for your collection.

This is a must have 222.8 gram Metal Ore Copper rich Impact Breccia from the famous Sudbury Astrobleme Impact Structure in Ontario Canada. Its dimensions are 110x70x10 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 pieces you'll ever own. 

About 1.87 billion years ago, an object from space nine kilometers in diameter slammed into Canada, a little north of Sudbury, Ontario creating the second largest impact structure on the earth. This impact was equivalent to a billion tons of TNT. An impact so big it cracked the earth, and in fact there are still earthquakes because of that event today!  The many mineral rich deposits and strange rock formations in such close proximity has attracted attention for 100's of years, long before its impact origin was known. 

Note that this is not a meteorite but a slice of Earth rock, altered by the impact of a very large meteorite.  This came from the ring of the impact and is the harder to find gold-copper-bronze colored impactite described as a metal-rich breccia and sulfides composed chiefly of some amount of iridium, cobalt & selenium. In addition, most of these specimens will contain nickel, iron, sperrylite and pentlandite as well as minor amounts of other metals, metallic & silicate minerals."

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

This is a beautiful combination of Apophyllite, Stilbite and Calcite on Chalcedony Druse. It is a large specimen at over 2 kg and has many double terminated 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. 

One of the distinguishing features of apophyllite is its ability to form well-defined crystals with a pyramid-like shape. These crystals often exhibit a prismatic or pseudo-cubic habit and have a vitreous luster. Apophyllite is transparent to translucent and is commonly found in colorless or white varieties, although it can also occur in shades of green, pink, yellow, or brown.

Chalcedony is a microcrystalline Quartz found in many different colours and patterns.  It has a number of crystals grouped under it many of which are very familiar, including Agate, Carnelian, Chrysoprase, Aventurine, Jasper and Onyx.

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. This huge crystal specimen would be a beautiful addition to any new or existing collection.

Himalayan Quartz refers to quartz crystals originating from the Himalayan mountain range, a region with complex geological activity. These crystals, found in various formations and sizes, exhibit clear to milky white coloration and may contain unique inclusions. The mining of Himalayan Quartz involves extracting crystals from the high-altitude regions of the Himalayas, often requiring careful and manual extraction methods due to the challenging terrain.

Believed by some to possess powerful energy, Himalayan Quartz is associated with enhancing meditation, promoting clarity, and balancing energy centers. Its association with the pristine Himalayan environment adds to its metaphysical significance.

The Puerto Minguez ejecta refers to the impact ejecta from the 38 million years old twin (multiple) impact structure Azuara / Rubielos de la Cerida in Northern Spain, originating from the nearby Rubielos de la Cerida impact structure.

This is a strongly deformed limestone component (seldom different rock types) with significant displacements. Typical clast deformation looks looking like a loaf cut into slices but not fully broken into pieces.  This is typical of a short-time dynamic deformation under high confining pressure.

The similar deformations are well known from the Ries crater impact ejecta that occurred in carbonate concretions and in the famous Ries Belemnites both embedded within soft Jurassic claystone. This sample shows a limestone clast partially sliced / fractured with prominent displacements in the range of up to 12 mm. The over all dimensions of this sample is 40x60 x125 mm and weighs 365 grams.

Amethyst is a purple variety of quartz, which is a mineral composed of silicon and oxygen. It is one of the most popular gemstones due to its beautiful color.  Amethyst ranges in color from light purple to deep violet. The color is caused by impurities of iron within the quartz crystal.  Amethyst can be found in various locations around the world, including Brazil, Uruguay, Russia, Zambia, and the United States.

Amethyst is believed to enhance spiritual awareness, ward off negative energies, promote balance and relaxation, and improve intuitive and psychic abilities. Amethyst is also thought to enhance mental clarity and focus.
