A variety of olivine that is yellowish-green. However, the name has been applied confusingly to various stones and it has been recommended that its use be discontinued; it was originally applied to any yellow stone, later it has been used as a misnomer in such compound names as 'Oriental chrysolite' (for yellow-green sapphire and yellowish-green chrysoberyl), 'Brazilian chrysolite' (for pale green chrysoberyl), 'Saxony chrysolite' (for greenish-yellow topaz), 'Syberian chrysolite' (for andradite), 'Ceylon chrysolite' (for tourmaline), and 'aquamarine chrysolite' (for beryl), and in the United States it has been used as a synonym for olivine and peridot. The stone resembles diopside. The name is derived from Greek chrysos (gold) and lithos (stone).
