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™ Black Hematite Mineral Specimen
Hematite specimen that is ideal for demonstrations in mineral physical properties.
Eisco™ Oligoclase Mineral Specimen
Oligoclase is a feldspar with high levels of sodium.
Eisco™ Igneous Rocks Kit with Storage Box and ID Card
A fun introduction to the world of geology through a 12-piece rock kit. Each Tech Cut specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features.

Eisco™ Labradorite Sedimentary Rock Specimen
Labradorite is a variety of plagioclase feldspar, intermediate between anorthite and albite. Notable about this species of feldspar is its potential for iridescence.
Eisco™ Garnet Mineral Specimen
Garnet forms under intense heat and pressure conditions, making it a common mineral in mountainous terranes.
Eisco™ Biotite Gneiss Specimen
Biotite Gneiss is high-grade metamorphic rock formed from other rocks undergoing alteration from intense heat and pressure.
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™ Gypsum Rock Specimen, 3cm
Gypsum is a sulfate mineral formed as the byproduct of evaporating saltwater. When this mineral becomes lithified, it forms rock gypsum, a sedimentary rock. These 3cm samples are great for use as classroom specimens or as a part of a small rock collection.
Eisco™ Raw Quartz, Mineral Specimen - Approx. 3 Inch
Quartz mineral specimen for use in classroom identification labs and exercises.
Eisco™ White Quartzite, Metamorphic Rock Specimen - Approx. 1 Inch - 10 Pack
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™ Labradorite Mineral Specimen
Labradorite is a variety of plagioclase feldspar, an intermediate between anorthite and albite.
Eisco™ Biotite Mica Mineral Specimen
Biotite Mica Specimen suitable for use in classroom identification lab exercises and for study on 2-plane, 90° cleavage.
Eisco™ Fluorite Mineral Specimen
Fluorite Mineral Specimen is used in classroom identification lab exercises and for study of uncommon 4-plane cleavage pattern.
