Spodumene
Though the gems of Spodumene have been discovered in the year 1877 but the mineral was found many decades earlier. The name of the gem is derived from a Greek word meaning "burnt to ashes".
Spodumene
Spodumene is a new mineral to science world discovered in the last three centuries. The gem variety of it was discovered only in the last 120 years.
Spodumene (Triphane)
Chemical composition -- Lithium aluminum silicate.
Color-- colorless, yellow, pink, violet, blue, green.
The name spodumene derives from the Greek meaning burnt to ashes describing the non-gem colorless or gray variety of spodumene. There are two varieties of spodumene considered "gem quality"; hiddenite and kunzite.
SPODUMENE
Overview: Spodumene is derived from the Greek, meaning "burnt to ashes," owing to the opaque, ash-grey appearance of material refined for use in industry.
Appearance
Sometimes found in other shades of color beside pink (kunzite) and green (hiddenite), these gems are simply called spodumene. Colors can range from colorless, yellow to green and lilac pink.

Spodumene from Laghman has also acquired a just fame. This region has produced some gem crystals of astonishing size (up to a meter long). The diversity of colors, purples, pinks and greens, is almost indescribable.

Spodumene occurs naturally in colorless, light to medium pink/lavender (Kunzite), and very rarely in a chromium colored, grass to emerald green stable variety known as Hiddenite.
Spodumene (lithium aluminium silicate) naturally occurs in colorless form as well as in yellowish-brown or greenish-yellow which is called "hiddenite," and in purple, pink or lilac which is called "Kunzite.

Spodumene’s color is due to trace elements of iron (producing yellow to green), chromium (producing medium to deep green) or manganese (producing pink to lilac), all substituting for aluminum in the crystal structure.

"Spodumene" furnishes pink to lilac "Kunzite," named after Dr. George F. Kunz, the gem expert, and for a time an emerald green variety was had from North Carolina which became known as "Hiddenite," after its discoverer, W. E. Hidden.
A variety of spodumene, Kunzite is magnificent deep pink lavender. It has been referred to as the “evening' stone; after exposure to the sun or hot lights, may have a tendency to fade. Most of the material is found in Afghanistan and Brazil.

This transparent gem is a pale-pink to lilac variety of the mineral spodumene (the other variety, hiddenite, is green).
It is a variety of the mineral spodumene. Kunzite can fade after prolonged exposure to light. Kunzite is also called "evening stone," because of its propensity to fade in bright light.
Kunzite is a pink to lilac colored variety of spodumene with minor to large amounts of manganese. It was named in honour of New York mineralogist and gemmologist George Frederick Kunz, who discovered it in California in 1902.
Kunzite is a transparent pink, light pink, or light purple gemstone and is a variety of the mineral spodumene. Kunzite can fade after prolonged exposure to light so is best worn at night.
Kunzite, a variety of spodumene, occurs in pale pink and in shades of violet ranging from pale to dark purple with a pinkish veil. Kunzite has a lively, vitreous gleam. This attractive mineral is relatively delicate. Kunzite is extremely fissile.
Kunzite is a gemstone variety of spodumene. It is known for a range of pink-violet to light-violet colors, but has also been identified in canary yellow, colorless, brown, and greenish-violet. On Mohs' scale of hardness, kunzite ranks 6.5 to 7.
The sodium pyroxene group is composed of jadeite, (NaAlSi2O6), aegirine (NaFe3+Si2O6), and spodumene (LiAlSi2O6), where lithium replaces sodium.
Even its name has American roots: t his pink gem variety of the mineral spodumene is named in tribute to George Kunz, the legendary gem scholar, gemologist, and gem buyer for Tiffany & Co at the turn of the century.

Many common minerals crystallize in this symmetry class, including azurite, clinopyroxene and clinoamphibole groups, datolite, epidote, gypsum, malachite, orthoclase, realgar, titanite, spodumene, and talc.
It was recognized in the year 1902 when it's first mine was discovered in California, USA that contained substantial deposits. It is one of the two varieties of the mineral spodumene, other being Hiddenite.
Example pyroxene species include the minerals enstatite (Mg2(Si2O6)), diopside (CaMg(Si2O6)), spodumene (LiAl(Si2O6)), and jadeite (NaAl(Si2O6)). The amphiboles include tremolite (Ca2Mg5(Si8O22)(OH)2), and glaucophane (Na2Mg3Al2(Si8O22)(OH)2).
