This gemstone is the youngest member of the spodumen family, to which the green or yellowish-green hiddenites, discovered about a quarter of a century earlier, also belongs. Hiddenites too bear the name of its discoverer, W. E. Hidden. Those who are interested in gemology will know that, together with dropsied, jadeite and three other kinds of mineral, the spodumens make up the pyroxene group, the word pyroxene being derived from the Greek words pry (fire) and xenon (stranger).
