Elbaite

Perfectly formed crystal, very limpid and lustrous, with the upper half pastel green without any veil and the lower half pink. Under halogen lighting, the c axis appears yellow-gold, and by rotating it under polarized light (such as that of an LED screen) the pink becomes purple and the pale bluish green becomes darker.
