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.

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).

Dimensions: 34x34x35 mm / 1.3x1.3x1.4 inches  (incl box)

This is a rare and fantastic 41.8 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 44x38x24 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.  Characterized by its yellow to greenish-yellow color, it lacks the aerodynamic shapes of tektites and often appears as irregularly shaped pieces. It is almost pure silica (around 98%) with very few impurities. Throughout history, it has been regarded as a mystical and powerful material, sometimes used in talismans and amulets.

This piece displays extremely well and is a quality translucent specimen. It has an aesthetic shape with a beautiful wind eroded body from the years spent in the Desert. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a 45.4 gram lot of beautiful tumbled Lapis Lazuli from Afghanistan.  There are 5 pieces that range in size from approximately 21-33x12-19 mm.  This is the exact lot that you will receive.

Lapis lazuli is a vivid blue metamorphic rock and a gemstone that has been prized for its intense color and historical significance for thousands of years.  It's composed of lazurite (for the blue color), calcite, sodalite, and pyrite. It is the presence of pyrite that causes the gold-colored flecks or veins in the stone.  It has a moderate hardness, typically ranging from 5 to 5.5 on the Mohs scale.  High-quality lapis lazuli has been historically sourced from mines in Afghanistan; however, other deposits are found in countries such as Russia, Chile, Italy, and the United States.

Lapis lazuli is believed to promote self-awareness and mental clarity.

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.

This is a must have 3-gram Impact Fallback Breccia from the Wanapitei Impact Crater at Wanapitei Lake, near Sudbury in Ontario Canada. Its dimensions are 37x13x5 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. 

Wanapitei Lake, located northeast of Sudbury, Ontario, is a 37-million-year-old meteorite impact crater, with its impact origin confirmed by the presence of suevite found in glacial drift surrounding the lake. Suevite is a type of breccia containing dark, vesicular glass formed under high-pressure shock metamorphism

Identified in the 1970s, the suevite at Wanapitei is a crumbly, shock-metamorphosed rock that often contains coesite, a high-pressure mineral diagnostic of impact structures.  The impact occurred during the Late Eocene epoch, roughly 37 million years ago. The crater is estimated to be 7 to 8.6 km in diameter, with the lake sitting on the edge of the much older and larger Sudbury Basin. The suevite appears very similar in composition to that found in the Ries crater in Germany, often containing bits of dark glass and partially melted clasts.

Note that this is not a meteorite but a slice of Earth rock, altered by a meteorite impact. A very, very large meteorite.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card. 

This is a rare and fantastic 2.4 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 19x14x11 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.
