The smoky-brown color of this beautiful calcite cluster is a result of trace impurities or microscopic inclusions incorporated during crystal growth. Iron, manganese, or tiny mineral inclusions can impart shades ranging from pale champagne to deep smoky brown. 

Donghai Mine, Jiangsu Province, China, is located within the Sulu ultrahigh-pressure metamorphic belt, one of the world's most geologically significant regions. Formed during the collision of two ancient continental plates hundreds of millions of years ago, the area contains rocks that were buried deep within the Earth before being uplifted to the surface. Later hydrothermal activity deposited mineral-rich veins throughout the region, creating exceptional crystals of quartz, fluorite, calcite, and other minerals.

Today, Donghai is internationally recognized as one of China's premier mineral-producing districts. In addition to quartz, the district is well known for its beautifully crystallized fluorite and calcite, valued for their vibrant colors, transparency, and excellent crystal form. Specimens from Donghai are prized not only for their beauty but also for the remarkable geological history they represent.

This is a natural "Ball Peen" Mica specimen from Branchville, Connecticut.  Instead of forming flat, book-like sheets as muscovite usually does, mica specimens from the Branchville Mica Mine develop a rounded, bulbous termination resembling the rounded end of a ball-peen hammer, from which its name is derived.

The Branchville Mica Mine, which has been inactive since 1944 and is mostly flooded, is one of the most historically important mineral localities in the United States. Opened in the 1870s as a mica mine, it quickly became internationally recognized for its scientific significance after Yale University mineralogists discovered an exceptional variety of rare minerals within its pegmatite. The quarry served as the type locality for several newly identified mineral species and played a key role in advancing the study of pegmatites and mineral formation. It is especially famous for producing the distinctive "ball-peen" muscovite crystals, along with fine specimens of beryl, spodumene, and other rare minerals. 

This classic specimen from Connecticut will come protected in a Perky Box.   The box will show its age but is just another way to show how old the specimen is.  The original label when the specimen was catalogued is also a nice touch.

This is a superb looking Garabato meteorite full slice weighing 4.79 grams and measuring 34x33x2 mm. This fresh H5 chondrite classified meteorite with 50% fusion crust was found September 23, 1995.  The total weight of the single stone is 160 Kg.  The meteorite was found while plowing.  

Would be a beautiful addition to any new or existing collection.  Will come with a Canagem Collection and a Naturalia specimen card.

This is an incredible green/yellow, fluorapatite crystal from Cerro del Mercado (Iron Mountain) in Durango, Mexico. It is completely free of the matrix and has a relatively perfect termination. The catalog number 2246 of this phantom specimen came from the Earl Calvert Collection.

At Cerro de Mercado, numerous veins containing gemmy, lemon-yellow to greenish fluorapatite crystals cut through the hematite massif. These crystals have been collected for decades from the area's iron mines, but they have become much more scarce with recent mechanization of the mining operations.

The bright, lustrous apatite crystals form hexagonal shapes with off-center terminations. They are found in vugs, often associated with quartz and calcite. Most crystals are around an inch in length, though larger crystals up to about 4 inches long have been found.

This is a superb individual Tsarev meteorite weighing 122.9 grams. Its dimensions are 58x44x40 mm. Twenty-eight specimens of this L5 classified meteorite were found in fields.  The largest mass weighs 284 kg, the smallest 761 gr with a total weight of 1.23 Tons. The greatest distance between the find sites was 6.0 km.

In 1968, amidst a global surge in conflicts, a remarkable discovery was made in a small village in Volgograd Oblast. This region, known as the primary site of the Battle of Stalingrad—one of the largest and bloodiest battles in history—yielded an extraordinary find in the quiet fields near the rural village of Tsarev.

The Tsarev meteorite, named after the Russian word for czar, is a stone meteorite responsible for one of the largest meteorite showers in Russian history. This meteorite shower occurred on December 6, 1922, but the stones were not discovered until 1968 and only recognized in 1979. The Tsarev meteorite's mineral composition matches that of ordinary chondrites, including olivine, orthopyroxene, clinopyroxene, maskelynite, calcium phosphates, nickel-iron, troilite, chromite, ilmenite, and rutile.

Academic analysis of the Tsarev meteorite reveals significant features: large grains of nickel-iron, light grey areas with well-preserved chondritic texture, and dark areas containing a matrix with olivine grains and remnants of chondrules. 

This specimen would be a beautiful addition to any new or existing collection.  Will come with a Canagem specimen card.

This is a superb looking partial slice of a Dhofar 492 classified meteorite weighing 7.15 grams and measuring 35x20x4 mm. This rare H classified meteorite was found in Oman in 2001. The total weight of the single piece recovered is recorded as a very low 281 grams.  This meteorite has a weathering grade of 3, with no shock level recorded. This rare meteorite is 1 of only 114 approved meteorites classified as H, the majority of which were discovered in Antarctica.

This piece displays extremely well and would be a great addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a rare and fantastic 43.8 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 52x37x31 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.

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.
