Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level of mineral classification.

Olivines can range in hardness from 6.5 (fayalite) to 7 (forsterite). Thus, peridots can approach quartz gems in hardness. However, they are still sensitive to scratching from dust (which has a hardness like quartz). Furthermore, they have some susceptibility to stress fractures. Use protective settings for any peridot rings.
