This is a beautiful, black Biotite crystal book from Córdoba. Spain. This biotite has a classic crystal shape and attractive dark coloration.
Biotite is rarely considered a valuable mineral specimen, but it can accompany other minerals and compliment them. In Bancroft, Ontario Biotite forms large crystals with green apatite and hornblende. Single large plates or "books" of biotite can grow to considerable size and can make impressive mineral specimens.

This is a beautiful combination of Calcite and Stilbite on Apophyllite crystal cluster.
Calcite is found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. Stilbite is perhaps the most popular zeolite mineral for collectors. Stilbite is a handsome specimen with its pearly luster and sometimes colorful pink tints. Apophyllite is transparent to translucent and is commonly found in colorless or white varieties, although it can also occur in shades of green, pink, yellow, or brown.
This nice crystal specimen would be a beautiful addition to any new or existing collection.

This is a natural cluster formation of large calcite crystals with hematite inclusions. This piece has some white color to translucent crystals with areas of orange/red coloring from hematite inclusions, with sharp tabular crystal formations. There are some nicks and imperfections on a few crystals but would still shine in the proper setup. They don't take away from how interesting this piece is. Would be a nice addition to any new or existing collection.

Here we have for you a superb looking Dhofar 020 classified meteorite weighing 40.3 grams. Its dimensions are 56x37x14 mm. Found 10 March 2000 in Dhofar, Oman, in the Arabian Peninsula this H4/5 classified chondrite has a TKW of 256 Kg with a shock stage of S4 and weathering grade of W3 by the Russian Academy of Sciences, USSR.
The following is an excerpt from Mark Bostick's review of this meteorite: "Dhofar 020 is a ordinary stone chondrite meteorite. The meteorite is high in free metal and therefore falls in the H class. S4 tells it is highly shocked. Slices of the meteorite, show veins of the cosmic impact created mineral Ringwoodite, although fractures in the stone tend to hide this some. It almost appears to me to have splinted upon impact. The meteorite falls in 4-5 petrology class, a reference to how metamorphed the meteorite is from its original state. This is judged by studying a thin section of the meteorite, most visually at the chondrules, a feature unique to stone meteorite. In a thin section under polarized light, pyroxene chondrules seem more common then their olivine pair. Still some regions in the meteorite show scattered patches of bright olivine inclusions. These are fairly rare, at least on my thin section, and most of the meteorite's olivine and pyroxene, some of the easier things to see in a thin section, appear to have went through a metamorphism, and have "melted" into the matrix and are at times undistinguishable."
This piece displays extremely well showing a beautiful crust, superb shape and good size. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
This is a fabulous 8.69 gram Sericho Pallasite Main Group meteorite, it measures 20x16x17. In 2016, two brothers were searching for their camels and came across several large, dense stones west of the village of Habaswein and south of Sericho, Kenya. Though recognized as meteorites in 2016, the masses had been known to camel-herders for decades. One village elder said that as a child, he and his brothers would play on top of the stones. It is classified as an Iron Pallasite main group with low weathering and is 1 of only 68 approved meteorites classified as such, with a recovered weight of about 2.8 T.
This piece displays extremely well and is a nice size showing great features. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
We have for you a small floater crystal of gypsum var Selenite in a perky box found 1962 in Ellsworth Mahoning County, Ohio U.S.A..
Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals and even trapped bubbles of air and water.
This specimen has no damage and will ship in its protective display box.
