A family of gemstones consisting of bright green hiddenite
, pink-lavender kunzite
and the stones which are just called spodumene (yellow-green or colorless). All spodumenes are difficult to cut (too much cleavage
in too many directions) and easy to break
if worn carelessly, but the feature that can make up for this is their trichroic
qualities -- three different shades of color
can show when the cut stone is viewed at different angles.
The gem-quality spodumenes were not discovered until the late 1800s (though non-gem samples of the family had been known for millennia for their burnt gray color; hence the name "spodumene" derived from the Greek for "burned to ashes").
