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 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
