An olivine volcanic bomb is a type of volcanic rock that contains olivine crystals and has been ejected during a volcanic eruption. Olivine is a mineral that is commonly found in the Earth's mantle and is one of the first minerals to crystallize as magma cools.
Volcanic bombs are large clots of lava that are ejected from a volcano during an explosive eruption. They can vary in size, and their shapes are often streamlined due to their molten nature as they are thrown through the air. When these volcanic bombs contain olivine crystals, they are referred to as olivine volcanic bombs.
Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Polylithionite and Aegirine from Poudrette Quarry, Mont Saint-Hilaire (MSH), Quebec, represent a classic mineral association from one of the world's most important alkaline intrusive complexes. Polylithionite is a rare lithium-rich mica that typically forms thin, lustrous hexagonal plates or rosettes with a silvery, pearly, or pale bronze appearance. It commonly occurs alongside Aegirine, which develops as long, dark green to black prismatic crystals Aegirine crystals that are often sharply terminated and may occur individually or in radiating spray. The contrasting crystal habits and colors create an attractive natural association that is characteristic of Mont Saint-Hilaire.
Specimens containing Polylithionite and Aegirine are valued for illustrating the unique mineral-forming environment of this geologically significant Canadian locality. It is the perfect combination for those looking for a unique and beautiful addition to their mineral collection!

This is a specimen of Star Mica or Muscovite and Quartz cluster. These clusters show crystals that grow in sheets or book formations. It is silvery gold with good transparency when held up to the light. The name Muscovite comes from the term Muscovy Glass which was a name for the thick sheets of Mica used as a substitute for glass Russia. The name Mica is derived from the Greek word that means to split.
On this nice specimen, the matrix faces are covered with beautiful golden yellow point stars of muscovite mica, a typical shape for this rare mica formation. The stars are the result of twinning; the points show a bit of wear but this does not detract from the beauty of such a piece.

This combination of Serandite and Aegirine from Poudrette Quarry, Mont Saint-Hilaire (MSH), Quebec, is considered one of Canada's classic mineral associations. Renowned for its extraordinary mineral diversity, this quarry has produced some of the world's finest specimens of both minerals. Serandite forms beautiful salmon-pink to orange-pink prismatic crystals, while Aegirine grows as glossy black, often sharply terminated blades, that may occur individually or in radiating sprays. These minerals are often accompanied by white Albite or Analcime, producing beautiful specimens.
Serandite is the signature mineral of Mont Saint-Hilaire and is the most sought-after species coming from that locality. This beautiful crystal cluster would be a great addition to any new or existing collection.

At the War Eagle Mine near Creede, Colorado, argentiferous tetrahedrite is a silver-bearing copper-antimony sulfide mineral found in polymetallic vein deposits. Its presence underscores the mine’s polymetallic character and its potential interest for both mineral collectors and exploration geologists.
The War Eagle Mine is a notable but inactive gold mine in Gilpin County, Colorado, with a rich geological setting and historical ties to the region’s mining heritage. It is located in a remote, forested area and is not accessible to visitors.
This specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

Heulandite is one of the most common and well known members of the Zeolite Group. It has a nice pearly luster and lovely colored hues. It forms wonderfully complex and quite unique crystals and is often associated with other rare and beautiful minerals.
Green heulandite is a naturally occurring and is prized for its vibrant green color, glassy luster and well-formed tabular crystals. Found primarily in the basalt cavities of the Deccan Traps in Maharashtra, its distinctive green hue is typically caused by microscopic inclusions of the mineral celadonite rather than the heulandite itself. It commonly occurs alongside minerals such as apophyllite and stilbite.
