Spodumene was discovered in Brazil in 1877, although in 1879 both Kunzite (pink from manganese) and Hiddenite (green from chromium) which were found in the United States, were recognized as being varieties of Spodumene. Spodumene is also called Triphane in the gem trade, mostly referring to the white and yellow color varieties.
Hiddenite was discovered by William E. Hidden, near what is now called Hiddenite, North Carolina. This material was named after Hidden. Hiddenite is most often faceted in an emerald shape, due to its crystal structure. This material is now mined in Myanmar, Afghanistan, Pakistan, Brazil, Madagascar, North Carolina and California.
Spodumene varieties are relatively hard, with a hardness of seven just like quartz. However, Spodumene varieties should be handled with care because, like diamond, it has a distinct cleavage. A sharp blow, if it lands in the wrong place, can break it in two. Spodumene varieties should also be protected from heat as well as continued exposure to strong light which may gradually fade the color. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
Hiddenite and Kunzite are faceted more often for gem collectors than the jewelry trade, for two reasons: the material is fragile and has a tendency for the colors to fade due to prolonged exposure to light.
