Here is the corrected text: Raw Red Sandstone Specimen - Single Sample, 1" in length. Sandstone is composed of well-sorted and well-rounded grains of quartz, indicating that the clasts in the rocks have traveled a long distance from their source and were heavily eroded along the way. The red coloration is due to the inclusion of iron in the chemical structure of the rock. This specimen is excellent for classroom mineral study and identification, ideal for students to compare with white sandstone to understand the physical expression of chemical differences. While each specimen will vary slightly in shape, size, and color, it will measure approximately 1" in length. Each is individually packaged, labeled, and barcoded for easy identification and storage. Selected and processed by a geologist, each and every specimen is hand-picked to ensure 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.
