Chondrules are peculiar rounded granules of some mineral, usually enstatite or chrysolite, found imbedded more or less abundantly in the mass of many meteoric stones, which are hence called chondrites. Research Chondrules
Chrysoberyl is a mineral occurring in granite rocks, pegmatites, and in mica schists. It is frequently found in river sand and gravels in round pieces about the size of a pea, but also crystallized in eight-sided prisms.. It serves as a gem stone: cymophane, orientalchrysolite, alexandrite and 'cats eye' which can be of great value. It has the formulae BeAl2O4 and a relative hardness of 9. *Chrysocolla
Chrysocolla is a hydrous silicate of copper, occurring massive, of a blue or greenish blue colour. It is a minor ore of copper and a mineral of secondary origin, occurring in the oxidised zones of copper veins. It is associated with malachite, azurite, cuprite, native copper. It is named from two Greek words meaning 'gold' and 'glue'. Research Chrysoberyl
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. Research Chrysolite
