EISCO - Raw Quartz, Mineral Specimen - Hand Sample - Approx. 3"- Geologist Selected & Hand Processed - Great for Science Classrooms

Raw Quartz SpecimenSingle Hand Sample, 3"One of the most abundant minerals on Earth. The tightly packed framework of silica tetrahedral that makes up this mineral gives it a high hardness of 7, a lack of cleavage planes, and a distinct euhedral crystal habit. Excellent for classroom mineral study and identification. A must-have mineral for any specimen collection. Quartz is useful during lessons on mineral hardness, luster, and fracture.While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, 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.Technical SupportAlways feel free to reach out to our team of scientists and geologists for additional information, or to assist you with any questions regarding our rock and mineral samples.
