Gemology
Peridot was called "evening emerald" by the Ancient Romans.
Peridot is the gem-quality olivine mineral. The mineral, olivine, is a silicate, and its crystal structure is made up of single isolated tetrahedral crystals.
Pure Peridot is rare, as it is unstable when released to Earth's environment, befitting to Peridot's reaction to Earth.
Olivine is often found in meteorites, though not exclusively, possibly a reference to how Peridot became stranded on earth in her escape pod.
The gem Peridot is often very small. Peridot, with her Limb Enhancers is around Pearl's height, whereas without it, she is inches taller than Steven.
Peridot, along with alexandrite and sardonyx, is the birthstone of August. It is the planetary stone of Saturn.
Peridot is one of the few known gemstones that can be found only in one color, although the shades of green may vary from light yellowish to dark brownish-green.
Peridot is often associated with good luck, peace and success.
An olivine's (and, by extension, Peridot's) chemical formula is (Mg, Fe)2SiO4, where the iron and magnesium combination gives it a light to olive green color. It's composed of:
Forsterite (Mg2SiO4).
Fayalite (Fe2SiO4).
Peridot is sometimes referred to as "the morning emerald" or "poor man's emerald".
Peridot is an idiochromatic gem, meaning its color comes from basic chemical composition of the mineral itself.
Peridot is also associated with power, influence, healing
