Rock and Mineral Specimens and Collections
Eisco™ White Quartzite Metamorphic Rock Specimen
Quartzite is formed from sandstone that has been tightly compressed to the point where the clasts have recrystallized to form a new rock. This formation mechanism, coupled the inherent strength of quartz, makes quartzite a very durable rock.
Eisco™ Corundum Mineral Specimen
For study of mineral hardness and crystal habit - EISCO Corundum Mineral Specimen is used in classroom identification labs and exercises, correlates well to Next Generation Science Standards Evidence Statements.
Eisco™ Chorite Mineral Specimen
Chlorite is a metamorphic mineral that has undergone light alteration. During metasomatism, phyllosilicate minerals may become hydrated and form chlorite.
Eisco™ Raw Chlorite, Metamorphic Mineral Specimen - Approx. 3 Inch
Chlorite is a metamorphic mineral that has undergone light alteration. During metasomatism, phyllosilicate minerals may become hydrated and form chlorite.
Eisco™ Labradorite Mineral Specimen
Labradorite is a variety of plagioclase feldspar, an intermediate between anorthite and albite.
Eisco™ Oligoclase Mineral Specimen
Oligoclase is a plagioclase fledspar that exemplifies many mineral physical properties including hardness, cleavage, and luster.
Eisco™ Mica Garnet Schist Specimen
Mica Garnet Schist Specimen for use in lessons on metamorphic rock properties, classification, and identification.
Eisco™ Streak Plates for Minerals
The off-black, unglazed porcelain of these streak plates show a mineral's color in powder form, or to identify the mineral content of a rock.
Eisco™ Serpentinite Metamorphic Rock Specimen
When clay- and aluminum-rich rock is altered by water from geothermal systems, serpentinite is liable to form. Serpentinite is often found in low-grade metamorphic areas and is formed when clay and aluminum rich rock is altered by water from geothermal systems.
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.
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.
