This is a specimen of Strontianite and calcite crystals on matrix from Mandata, Pennsylvania.  Strontianite is a rare mineral made mostly of strontium carbonate and is an important source of the metal strontium. It usually forms in hydrothermal veins and limestone deposits, often found alongside minerals like calcite and fluorite. Strontianite can appear in different colors, including white, gray, yellow, green, or brown, and has a glassy or slightly shiny look. It was first discovered in Strontian, Scotland, which is how it got its name, and it can also be found in Germany, Italy, China, and parts of the United States. This mineral is mainly used to extract strontium, which is important for making red fireworks, ceramics, and special types of glass.

The top of the specimen is an exposed vug containing four sharp strontianite crystals sitting on a bed of small transparent calcite crystals. The strontianite fluoresces strongly white under long wave UV.  The specimen is in excellent condition.

This is a fantastic crusted 26.1 grams NWA (Northwest Africa) 869 L3-6 classified meteorite Individual found by Nomads in the Sahara Desert. The dimensions of the specimen are 46x24x16 mm.

NWA 869 classified meteorites can still be interesting and this one is for sure perfectly shaped to catch your attention. It displays a superb crust on most of its surface.  Most samples are individual meteorites but some fragments (mostly >1 kg) also occur. In most cases the fusion crust has been polished or ablated by wind erosion. Many samples are more severely affected and show faces with deep wind erosion features. Fracture faces, formed by ground collision, show a typical gray-green color and sometimes visible brecciation (light and/or dark clasts).

Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a great 34.2 gram Red Suevite Fallback Breccia from the Sääksjärvi crater in Finland. It has dimensions of 76x39x6 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. The enormous heat and pressure at the impact explosion created an interesting melt, a Suevite, and shattered rocks and dust which fell back into the crater area becoming cemented together over the centuries.  These rock formation is known as Fallback Breccia.

These are some of the best looking breccias we've found. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a rare and fantastic 26.8 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 51x40x25 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.

Here we have for you an amazing 1.2 grams premium shaped Irghizite Tektite from the Zhamanshi Crater in Kazakhstan. Its Dimensions are 28x8x5 mm.  These specimen were first found in 2003 and date back 900,000 ± 100,000 years.

This stretched and twisted Irghizite is typical of this material. Unlike other Tektites which can be found hundreds of miles from their point of origin, this is found in and around the crater formed by the impacting body.  In this case it is speculated to be of cometary origin due to analysis of the elements contained within the Irghizites and other impactite found in the crater which are called Zhamanshinite.

This piece displays very well and is a very nice size showing multiple characteristics of its origin.  Would be a beautiful addition to any new or existing collection. Comes in a small specimen box and with a Canagem Collection specimen card.

Prehnite is a green to yellowish-green colored mineral that belongs to the phyllosilicate family. It is composed of calcium, aluminum, and silicate, with traces of iron, magnesium, and other elements. Prehnite crystals have a unique pearly luster and can form in a variety of shapes, including tabular, prismatic, and stalactitic formations.

Prehnite is believed to have a calming effect on the mind and emotions, promoting relaxation and inner peace. It is also said to be a stone of unconditional love, compassion, and healing.

These Prehnite clusters originate from Africa.  The dimensions of the clusters are listed below:

A:  31x24x20 mm/1.2x0.9x0.8 in | 20 gr/0.7 oz | 100.5 carats
B:  42x28x24 mm/1.6x1.1x0.9 in | 36 gr/1.3 oz | 182.5 carats
C:  43x32x31 mm/1.7x1.3x1.2 in | 59 gr/2.1 oz | 295.8 carats

This is a must have 25.3 gram Impact Melt Rock from the Stac Fada Member Impact Structure, NW Scotland. It measures 74x31x6 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 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 beautiful Impact melt rock comes from the Stac Fada impact structure in Scotland. The structure has an estimated age of about 1.2Ga (1,200 Ma). The Stac Fada Member of the Precambrian Stoer Group in Scotland has previously been described as volcanic in origin. However, shocked quartz and biotite provide evidence for high-pressure shock metamorphism, while chromium isotope values and elevated abundances of platinum group metals and siderophile elements indicate addition of meteoritic material. Thus, the unit is reinterpreted as having an impact origin.

This gorgeous slice displays very well.  Would be a beautiful addition to any new or existing collection. Comes with two 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 is a must have 80.5 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 87x73x6   mm.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
