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.

Weight: 38.4 Grams / 1.3 Ounce
Details: Volcanic activity Mortlake, Victoria, Australia
This is a great 85.2 gram Impact Melt Breccia from the Sääksjärvi crater in Finland. It is amazingly light considering its mass of 95x51x15 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 item 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.
Sääksjärvi is a lake in Kokemäki, Satakunta, western Finland, east of the town of Pori. The lake is notable because it overlies an impact crater. The crater is 5 kilometres (3 mi) in diameter and is completely buried under the lake and is not visible at the surface. The age of the impact structure is estimated to be about 543 ± 12 Ma (million years ago), at the boundary between the Ediacaran and Cambrian periods. There are impactite rocks in the southwestern region from the crater confirming its extraterrestrial origin. At the time of its discovery, only one impact crater (Lappajärvi) was known in Finland.
Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Size: 15.6x12mm
Shape: Oval Cut
Color: Clear White with Golden Needles

Rutilated Quartz is a beautiful variety of Quartz that contains needle-like inclusions of the mineral Rutile. These golden, coppery, or silver-colored needle inclusions create unique patterns within the Quartz.
Rutilated Quartz is thought to amplify energy, enhance clarity and intuition, facilitate spiritual connection, provide protection, and promote healing and manifestation.

This is an outstanding specimen Impact Melt Glass, or "Flädle" glass, from the Lake Mien crater, 12 km (7.5 mi) southwest of the town of Tingsryd, Sweden. It weighs 39.8 grams and measures 54x49x20 mm. Although not a meteorite, impactites are directly linked to them and their impacts.
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 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 eroded crater is marked by a 5.5-km (3.4-mi) diameter circular lake named Lake Mien. The original crater rim is estimated to have been about 9 km in diameter before erosion. Its age is estimated to be 121.0 ± 2.3 million years (Early Cretaceous). This Suevitic breccia with clastic matrix and melt inclusions (black) and crystalline rock clasts (gray to white) is amazingly light considering its mass. It has a unique hollow sound when you tap it.
Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
This is a must have 506.7-gram Impact Melt Breccia, also referred to as Suevite, coming from Zipplingen and the famous Ries crater Germany. 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 14.5 million years ago in Malmian or Jurassic limestone when a meteorite crashed into the earth making a ~10 miles wide crater named the Ries crater in Germany. This gorgeous end piece displays very well and shows typical inclusions of glass bomb as the dark material and crystalline fragments visible throughout the specimen showing the stages of shock metamorphism.
It is amazingly light considering its mass of 130x109x37 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
Fine crystal cluster of Quartz points surrounded by many Bornite and Pyrite crystals from the famous Leonard Mine at Butte. The nubby, matte-finish bornite crystal clusters are attractively scattered across the specimen with contrasting brassy pyrite crystals and quartz crystal points.
This top specimen is in very good condition. Would be a beautiful addition to any new or existing collection.

This is a must have 96.3 gram Impact Breccia, also referred to as Suevite, 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 end cut displays very well with a mass of 89x62x19 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
