Rock and Mineral Specimens and Collections
Eisco™ Hematite Mineral Specimen
This specular variety of hematite takes the form of tiny, sparkling iron oxide crystals.
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.
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™ Travertine Sedimentary Rock Specimen
Travertine is a carbonate rock formed from gushing hot springs. The airy, porous material indicates an abundance of air bubbles moving through the rock as it solidified. Travertine is unique in that it forms as a result of rapidly dropping pH levels.
AquaPhoenix Scientific Sandstone
This small sandstone specimen showcases classic sedimentary layering—ideal for teaching weathering, erosion, and rock classification.
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 Talc, gray
This 1.5 to 1.75 inches gray talc sample is ideal for teaching mineral hardness, texture, and identification in geology or earth science education.
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 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 Milky Quartz
This naturally opaque milky quartz sample is ideal for geology lessons, rock collections, and hands-on earth science education. Sized 1 to 1.25 in., each specimen showcases the common form of crystalline silicon dioxide.
