Spodumene - Wikipedia

Spodumene was first described in 1800 for an occurrence in the type locality in Utö, Södermanland, Sweden. It was discovered by Brazilian naturalist Jose Bonifacio de Andrada e Silva . The name is derived from the Greek spodumenos (σποδούμενος), meaning "burnt to ashes," owing to the opaque, ash-grey appearance of material refined for use in industry.

They are very sensitive to knocks and will chip if hit too hard. Spodumene is also strongly pleochroic, showing lighter and more intense coloring when viewed at different angles. Brown Spodumene is sometimes heat treated to transform the color into a more pink tone and produce Kunzite.

Spodumene: The mineral Spodumene (kunzite)

Spodumene is strongly pleochroic. The pleochroism is easily observed in many transparent crystals, where the color ranges from yellow to violet when viewed at different angles. Pink Kunzite will often exhibit a deeper pink color on crystal terminations due to the pleochroism. Spodumene can grow into enormous crystals. The largest single crystal found is a well-crystallized, 42 foot (12.8 meter) giant.

Spodumene was once the most important ore of lithium metal - until the late 1900s, when subsurface brines with high concentrations of lithium were developed in Argentina, Chile, China and other locations. These brines can be pumped to the surface, allowed to evaporate, and lithium is easily processed from the evaporite material. Today, very little lithium is produce from spodumene.

Pyroxene mineral Britannica

Substitution of Li + and Al 3+ for 2 Mg 2+ yields spodumene. The substitution of Al 3+ for Mg 2+ and Al 3+ for Si 4+ yields the ideal tschermakite component MgAlSiAlO 6. Other less common pyroxenes with compositions outside the pyroxene quadrilateral include johannsenite [CaMnSi 2 O 6], and kosmochlor (ureyite) [NaCrSi 2 O 6]. Johannsenite involves the substitution of manganese for iron in hedenbergite. Kosmochlor has chromium (Cr) in place of iron or aluminum in a sodic pyroxene.
