CHRYSOLITE

Chrysolite is a mineral, composed of silica, magnesia, and iron, of a yellow to green colour. It is harder than glass, but less hard than quartz; often transparent, sometimes only translucent. Very fine specimens are found in Egypt and Brazil, but it is not of high repute as a jeweller's stone. It is common in certain volcanic rocks and is sometimes used as a gem. The name was also early used for yellow varieties of tourmaline and topaz.
