    Eucryptite is a lithium bearing aluminium silicate mineral . It is neither polymorph nor isomorph of olivine. Because it crystallises in trigonal crystal system while olivine crystallise in orthorhombic crystal system. Eucryptite is a secondary alteration product of Spodumene ( Li bearing pyroxene).
