Raw Olivine Mineral Hand Sample, Approx 3 inch

This raw olivine mineral specimen is a hand sample measuring approximately 3". Olivine is a major component of oceanic crust and, with the highest crystallization temperature of common minerals, is the first mineral to form in a cooling magma, making it a useful geothermometer. The specimen is well suited for identification and classification exercises, as well as lessons in hardness, fracture, and luster. Its massive, earthy habit provides a clear example of nonmetallic luster. Each specimen is selected and hand processed by a geologist, sourced from locations around the world, and processed in Victor, NY. The sample arrives individually packaged, labeled, and barcoded for easy identification and storage.
