Kunzite was discovered near the beginning of the twentieth century, in America, named for its discover, the gemologist G.F. Kunz. And although it does not have a very long history, its effectiveness has been tried and proven. Kunzite is a form of Spodumene, which occurs in a wide range of colors, although the most common color is the yellow gray (which is called triphane). Two other gemstone varieties, the lilac-pink kunzite (colored by manganese) and the bright emerald green hiddenite (colored by chromium) are very popular with collectors.
