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.

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.

Sulfohalite is a rare sodium sulfate mineral containing chlorine, fluorine, sulfur, and sodium, and is highly sought after by mineral collectors at Searles Lake, California. It is known for forming small, often transparent to translucent, yellow-green octahedral or dodecahedral crystals, often appearing as two pyramids stacked base-to-base.
Searles Lake, located east of Trona in San Bernardino County, California, is the type locality for sulfohalite, where it was first described by Hidden and MacKintosh in 1888. It is found within the evaporite sediments of the Searles Lake basin. While sometimes found in abundance, it can be rare and hard to find in other years, making it a prized specimen during collection events. Usually colorless, gray, or greenish-yellow, often with a greenish-brown tint. Typically occurs as yellow-greenish octahedral crystals. Crystals are generally small (thumbnail or micro size).
