Barite clusters are beautiful mineral specimens that feature intergrown crystals forming visually appealing arrangements. It is typically found as thick to thin tabular crystals, usually in clusters with the crystals growing parallel to one another, or nearly so. It can also occur as bladed, blocky, or even rosette-like aggregates. This is a fine cluster of blocky barite crystals. Would be a beautiful addition to any new or existing collection.

This is a must have 26.7 gram Impact Melt Rock from the Dellen Crater, north of Stokholm, Sweden. Some locals call these rocks by the name of “dellenites”, although officially they are impact melt rocks. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection items you'll ever own. Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite.
The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc.
This impactite was formed approx. 89 million years ago when a meteorite crashed into the earth making a round crater which is now a lake about 11 miles wide. Dellen impactites were divided into three impactite groups: (i) suevitic impact breccias with lithic and melt clasts, (ii) impact melt rocks, and (iii) shocked (parautochthonous) target rock. In turn, impact melt rocks were divided into (i) clast-rich, (ii) clast-poor, and (iii) clast-free types. The Dellenite type material was classified as clast poor impact melt breccia.
This gorgeous slice displays very well. It is amazingly light considering its mass of 70x32x8 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
This is a must have 29.55 gram Impact Breccia also referred to as Suevite coming from the famous Rochechouart impact structure in South Western France, near the village of Chassenon. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection items you'll ever own. Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite.
Named after the town of Rochechouart, the Rochechouart impact structure is located on the western margin of the French Massif Central near the city of Limoges, approximately 350 km (220 mi) south of Paris. Rochechouart (population about 3800) is built with rocks created or modified by the impact (impactites). Chassenon, a third of the size of Rochechouart, is also built of impactites. Impactite was used 2000 years ago for building Chassenon's monumental Roman baths of Cassinomagus.
The very fine materials (impactoclastites) are preserved forming a very fine layered horizontal deposits on top of the melt rich suevite (breccia with a debris matrix and both rock debris and melt fragments as clasts) near Chassenon.
The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc. This impactite was formed 186 million years ago. This deformed rock fragments and partly molten are imbedded in a melt matrix showing typical flow structures from former melt.
This gorgeous slice displays very well with a mass of 49x48x9 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
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.
This piece has been cut to showcase the beautiful green olivine crystals. It would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Pseudomorphs are mineral specimens that have the external shape of one mineral but are composed of another. The pseudomorph goethite after marcasite forms when marcasite is exposed to oxidizing conditions and starts to oxidize and break down. As the marcasite breaks down, goethite replaces it in the crystal structure, preserving the shape of the original marcasite crystal. The resulting specimen appears as a marcasite crystal, but is actually composed of goethite.
The Farafra Oasis, in the White Desert, has been known for a number of years to deliver incredible pseudomorph specimens. The pseudomorphs occur within the Cretaceous Khoman Chalk, from which the White Desert derives its name.
These specimens are remarkable for their relatively sharp marcasite crystal forms in aesthetic crystal clusters. They are in excellent condition. This collector's specimen is unique, of great quality and ready for display.
