Peridot (/ ˈ p ɛ r ɪ ˌ d ɒ t,-ˌ d oʊ / PERR-ih-dot, -doh), sometimes called chrysolite, is a yellow-green transparent variety of olivine. Peridot is one of the few gemstones that occur in only one color.
Peridotite is named for the gemstone peridot, a glassy green gem originally mined on St. John's Island in the Red Sea [65] and now mined on the San Carlos Apache Indian Reservation in Arizona. [ 66 ] Peridotite that has been hydrated at low temperatures is the protolith for serpentinite , which may include chrysotile asbestos (a form of ...
Peridot, a gem-quality olivine; Archaically, any of several green or yellow-green-coloured gemstones including Topaz, a silicate mineral of aluminium and fluorine; Chrysoberyl, an aluminate of beryllium; Zircon, a mineral belonging to the group of nesosilicates; Prehnite, an inosilicate of calcium and aluminium

The fragmented volcanic material (pyroclastics) of the tuff ring contains olivine, a silicate mineral containing iron and magnesium, also known as peridot when of gem quality. Olivine is a common mineral component of lava and is one of the first crystals to form as magma cools. [9]
Historic specimen of forsterite var. peridot, 1.3 cm × 0.7 cm × 0.4 cm (0.5 in × 0.3 in × 0.2 in). Mining of peridot seems to have begun around 300 BC. The island is considered geologically unique as it is uplifted mantle, a fragment of the sub-Red Sea lithosphere. Rocks on the island are mainly lower crustal igneous rocks.
Stranded on Earth after the events of the first-season finale, Peridot becomes a recurring antagonist in the first half of the second season before being eventually captured and convinced to ally with the Crystal Gems to defuse the Cluster. When the Crystal Gems first encounter her she wears technological "limb enhancers", which give her a ...
It consists of centimetre-sized olivine crystals of peridot quality in an iron-nickel matrix. Coarser metal areas develop Widmanstätten patterns upon etching. Minor constituents are schreibersite, troilite, chromite, pyroxenes, and phosphates (whitlockite, stanfieldite, farringtonite, and merrillite). [1] [2]
