Various Peridot

A bit larger faceted drops of Peridot in a lovely lime green colour and a couple of grass grren ovals (below). The drops is faceted by hand and their form and size varies, but if you order a pair I'll promise to åick two of a kind. The three ovals was acquired some time ago and for a while I thought them to be Crome Diopside due to the dark colour.None of the stones have any visible inclusions. One of the larger ovals in prepared with a Pretty Ogr 925 Sterling silver basket claw setting.

Peridot is gem-quality olivine. The origin of the name peridot is uncertain. The Oxford English Dictionary suggests an alteration of Anglo–Norman pedoretés (classical Latin pæderot-), a kind of opal, rather than the Arabic word faridat, meaning "gem". Peridot is one of the few gemstones that occur in only one colour, an olive green. The intensity and tint of the green, however, depends on how much iron is contained in the crystal structure, so the colour of individual peridot gems can vary from yellow—to olive—to brownish-green. The most valued colour is a dark olive-green. Peridot is sometimes mistaken for emeralds and other green gems. In fact, notable gemologist George Frederick Kunz discussed the confusion between emeralds and peridots in many church treasures, notably the "Three Magi" treasure in the Dom of Cologne, Germany. Olivine, of which peridot is a type, is a common mineral in mafic and ultramafic rocks, and it is often found in lavas and in peridotite xenoliths of the mantle, which lavas carry to the surface. Peridot can be also found in meteorites.

Peridot is mined in Arkansas, Arizona, Hawaii, Nevada, and New Mexico in the US; and in Australia, Brazil, China, Egypt, Kenya, Mexico, Myanmar, Norway, Pakistan, Saudi Arabia, South Africa, Sri Lanka, and Tanzania. Its possible that Peridot have originated in very antique jewelry from Egypt, where the reuse of stones from ancient objects was common during the 17- and 1800 century. Peridot crystals have been collected from some Pallasite meteorites. A famous Pallasite was offered for auction in April 2008 with a requested price of close to $3 million at Bonhams, but remained unsold. The largest cut peridot olivine is a 310 carat (62 g) specimen in the Smithsonian Museum in Washington, D.C.

Peridot is the birthstone for the month of August.
