Olivine Specimen

An olivine specimen that is pear-shaped, scalloped, and tumble polished, and displayed in a copper cannister. The copper canister is clear-coated to slow the tarnishing process. The olivine is scalloped for safe-handling; scalloping makes the specimen easier to grip when being handled, which reduces the possibility of slipping out of one's hand. Olivine itself is a common mineral, but a less common form of it is forsterite, from which gem quality peridot is obtained.
