Named for Ernst Ludwig, an Austrian Professor of Chemistry at the University of Vienna in Austria who was the first to analyze the type material. Ludwigite is a somewhat uncommon, but widespread mineral that can be found in Romania, Italy, Scotland, Sweden, Russia, Iran, the United States, Canada, and North Korea, among others. Typically, Ludwigite occurs in magnesian iron skarn and in contact metamorphic deposits. It is likely that Ludwigite is weakly ferromagnetic, a naturally permanent magnet.
In this specimen, multiple layers of compact black fans and patches of Ludwigite in a greenish white matrix, possibly another borate mineral. This specimen from the Mountain Lake Mine is an interesting addition to any mineral collection.
Name: Ludwigite
Specimen Size: Miniature-Sized
Dimensions: 49x49x45 mm / 1.9x1.9x1.8 inches
Weight: 171 Grams / 6.0 ounces
Origin: Mined in Mountain Lake Mine (Jack Mine), Great Western Mine Group, Brighton, Big Cottonwood Mining District, Salt Lake County, Utah, USA
This is a great fragment of the NWA 1459 meteorite which is classified as a stone achondrite, Diogenite-olivine. It weighs 0.044 grams. This rare meteorite was found in April of 2002, and called by the Hupe the world's rarest classification as an Olivine Diogenite.
Mr Hupe said at the time: "This meteorite featured in the October 2002 issue of Meteorite! Magazine represents the first non-Antarctic meteorite to fall into this exclusive group. A total known weight of 49 grams is officially recorded for this find. Being millions of times rarer than diamond, extreme patience was exercised for the cutting operation. About two and a half grams was lost during the first cut and polishing because we did not possess knowledge of its extreme rarity at that time. Another one and a half grams was provided to four contest winners and a web site promoter. Trying to preserve a main mass of 30 plus grams will leave less than two grams available for private purchase unless a contest winner is willing to part with some of their material. This specimen running on eBay may be your only opportunity to add the world's rarest class to your type specimen collection. Remember, there is no other type of meteorite available in the world that can come close to the rarity represented by this specimen not even a Chassignite, an Angrite or even a Lodranite."
This piece is a very desirable type of material and a great specimen all around. The specimen comes in a display box and is accompanied by a Hupe Collection and a Canagem® Collection card. Would be a beautiful addition to any new or existing collection.
Here we have for you a nice looking end cut of a Sahara Desert NWA unclassified meteorite weighing 55.8 grams. Its dimensions are 47x33x29 mm. This never classified Northwest Africa stone was found in the Sahara Desert around 2000.
It's a good quality cut NWA meteorite specimen showing interesting internal structure (L5?) and attractive mottled interior with chondrules and metallic flakes. 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.
This is a fantastic crystallized chalcopyrite matrix core sample. The specimen is rounded with brassy chalcopyrite, pyrite and grossular crystals. The Grasberg mine has the single largest known gold reserve and the second largest copper reserves in the world. It is located 96km north of Timika, at Tembagapura in Irian Jaya – the most easterly of Indonesia’s provinces – on the western half of the island of New Guinea. The mine stands at the collision of the Indo-Australian and the Pacific tectonic plates.
The Grasberg minerals district includes open-pit and underground mines. The mining of the final phase of the Grasberg open pit was completed in 2019 and the mine transitioned from open-pit mining to large-scale underground mining.
A mine core sample is a cylindrical piece of rock, often several inches in diameter, extracted from the earth by a drilling rig to explore for pyrite deposits. These samples are used to physically examine the rock's geology, identify different mineral types like pyrite, and measure their abundance and distribution. Core samples are critical for determining the economic viability of a mine and are analyzed using methods such as visual inspection, microscopic examination, and chemical techniques.
This top specimen is in perfect condition. Would be a beautiful addition to any new or existing collection.

This Pectolite specimen comes from the Poudrette Quarry at Mount-Saint-Hilaire and displays a nice terminated crystal.
Pectolite crystals are known for their unique crystal habits, often forming as slender and elongated fibers radiating from a central point. These fibers can be densely packed to form globular masses. Pectolite can be tough and dense but is often delicate and soft to the touch. It can tarnish brown or black upon exposure to air. The crystals can be found in various colors, including white, gray, light yellow, brown, pink, orange, salmon, and light blue. The blue variety, known as Larimar, is highly sought after and is found exclusively in the Dominican Republic. Pectolite is primarily used as a collector's mineral.
Great looking translucent crystal cluster, an excellent specimen from the world renowned location that is MSH. This beautiful crystal would be a great addition to any new or existing collection.
Name: Pectolite crystal
Specimen Size: Thumbnail-Sized
Dimensions: 28x14x7 mm / 1.1x0.5x0.3 inches

Peruvian pyrite is famous worldwide for its well-formed, highly lustrous crystals. The country is one of the top sources for high-quality pyrite specimens, particularly from the Huanzala Mine in the Áncash Region and the Quiruvilca Mine in La Libertad. These locations produce stunning pyritohedral crystals, often found in association with quartz, sphalerite, and galena. The entire top of the specimen is covered with many sharp brassy pyrite crystals with some smaller white quartz crystals.
The term “pyritohedral” refers to a specific crystal habit that pyrite (and occasionally other minerals) can form. In this structure, the crystal takes on a polyhedral shape with 12 faces. However, unlike a perfectly symmetrical shape with identical pentagonal faces, natural pyritohedral crystals often exhibit slight irregularities or distortions in their faces.
Pyrite is known as a stone of protection, abundance, and confidence. It is believed to shield against negative energy and promote mental clarity and willpower.
This great Peruvian specimen is in very good condition. Would be a beautiful addition to any new or existing collection.
