Peridot, is the common name for the green-to-yellow gem variety of olivine. Olivine is a group of simple orthosilicates, which forms a solid-state solution series (meaning that iron and magnesium substitute freely in the crystal structure without altering it), with iron-rich fayalite at one end and magnesium-rich forsterite at the other. Most peridot is about 90% forsterite. Olivine is believed to be a major component of the Earth’s upper mantle (the viscous layer that allows the continents to drift), and is therefore probably one of the most abundant minerals on the planet. It forms volcanically, usually in mafic or ultramafic lavas, and sometimes as volcanic “bombs” released explosively from volcanoes. Well-formed crystals are rare, but when they do form they are tabular with wedge-shaped terminations.
Chemical Formula: Mg2SiO4
Primary Birthstone for Virgo (23rd August - 22nd September), Secondary Birthstone for Leo, Scorpio and Sagittarius
Aligns with the Upper Heart and Heart Chakras; Affects the Solar Plexus and Sacral Chakras
Properties: Peridot was used in Ancient Egypt for jewellery and healing from 4000 years ago. In the Middle Ages it was used for warding off evil spirits and to bestow wisdom and friendship. It connects with the Upper Heart and Heart Chakras, and its light, gentle energy is balancing, mood-lifting and detoxifying. It strengthens the immune system, and is particularly good for filtre organs, especially liver and kidneys. It can also be used to treat skin complaints, both by wearing and also by bathing in its crystal water. Peridot nurtures, gives a sense of being "held in light", and also of inner flow, helping us to feel calm, still and optimistic.
