Rock and Mineral Specimens and Collections
Eisco™ Raw Fluorite, Mineral Specimen - Hand Sample - Approx. 3 Inch
Fluorite Mineral Specimen is used in classroom identification lab exercises and for study of uncommon 4-plane cleavage pattern.
Eisco™ Raw Phyllite, Metamorphic Rock Specimen - Approx. 3 Inch
Phyllite Specimen for demonstrations of metamorphic properties, such as glossy sheen and dense, foliated minerals.
Eisco™ Chalcopyrite Mineral Specimen
From the same family as fool's gold, Chalcopyrite is a yellow crystalline mineral consisting of a sulfide of copper and iron. It's the principal ore of copper formed in hydrothermal veins.
Eisco™ Albite Specimen
Albite is a variety of plagioclase feldspar that is rich in sodium. With a glossy sheen, 2 planes of cleavage, and a standard hardness of 6, this mineral is a classic specimen for lessons in mineralogy and petrology. Useful when trying to distinguish from other feldspars.
Eisco™ Oolitic Limestone Specimen (Sedimentary Rock)
Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids.
Eisco™ Magnetite Mineral Specimen
Magnetite grains align themselves with the earth's magnetic field, preserving a record of the field's direction when forming igneous rocks.
Eisco™ Syenite Igneous Rock Specimen
Syenite is a variety of felsic igneous rock heavily composed of feldspar. Though formed similarly to granite, the higher aluminum content of syenite indicates a more evolved magma.
Eisco™ Green Slate Metamorphic Rock Specimen
Green slate is a very lightly metamorphosed and well-foliated specimen. It can be distinguished from it's parent rock (Shale) by the difference in pitch when struck.
Eisco™ Dolostone Sedimentary Rock Specimen
Dolostone is a lithified form of dolomite. Composed primarily of carbonate material, dolostone is a more stalwart rock than its chemical cousin, limestone. It is often mined for construction and infrastructure purposes.
AquaPhoenix Scientific Biotite Mica
Explore the dark, flaky sheets of biotite mica with this 10-pack of 0.75 to 1 in. samples—perfect for mineral identification and classroom geology kits.
AquaPhoenix Scientific Quartz, Rose
A pink rose quartz sample measuring 1 to 1.25 inches, perfect for geology lessons, crystal studies, or classroom rock collections.
AquaPhoenix Scientific Corundum
This 1 to 1.25 inches corundum specimen is an excellent example of one of the hardest minerals on Earth—perfect for classroom use and hardness testing.
AquaPhoenix Scientific Pink Feldspar
Naturally pink feldspar with visible crystal structure—used to teach mineral properties, rock classification, and Earth science fundamentals.
Metamorphic Rock Collection
15 Specimens demonstrate how heat, pressure, and chemical action affect rocks.
