12 Pack - Raw Gypsum, Mineral Specimens - Approx. 1"

• GYPSUM | A sulfate mineral that often forms from evaporating lakes in what is known as an evaporite deposit. Crystals grow into soft, wide sheets, but gypsum is also commonly found filling veins and fractures in other rocks
• GREAT FOR GEOLOGY CLASSROOMS | Gypsum is one of the standards on the Mohs hardness scale, and its similar appearance to other minerals makes it useful in identification exercises. This set of six samples is excellent for group study and examination
• GEOLOGIST SELECTED | Each specimen is selected and hand processed by an actual geologist, ensuring each sample exhibits defining features
• LOCALLY PROCESSED | Our rock and mineral samples are sourced from a variety of locations around the world and are processed in Victor, NY
• LABELED PACKAGING | Set is packaged in a transparent bag, and is labeled & barcoded for easy identification

Raw Gypsum Specimen
Set of 12 Samples, 1"

A sulfate mineral that often forms from evaporating lakes in what is known as an evaporite deposit. Crystals grow into soft, wide sheets, but gypsum is also commonly found filling veins and fractures in other rocks. Ideal for identification & classification exercises. Gypsum's perpendicular planes of cleavages make it an excellent tool for studying 2-plane, 90° cleavage.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Set is packaged in a transparent bag, labeled & barcoded for easy identification and storage.

Selected & Processed by a Geologist.
Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.
