Product Overview
Much of the earth's surface is covered in oceanic crust, of which olivine is a major component. With the highest crystallization temperature, olivine is the first mineral to form in a magma, making it a useful geothermometer. Ideal for teaching students about rounding and sorting, as well as for identification & classification exercises, and is great for lessons in hardness, fracture & luster. Its massive earthy habit is a perfect example of nonmetallic luster. 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.
