About Kornerupine Cat’s Eye
Kornerupine Cat’s Eye is a rare gemstone that is available in shades of green, bluish green, yellowish green and yellowish brown. The most desirable gems are the emerald green gems from Sri Lanka and Tanzania that are coloured green by the presence of vanadium. Beautiful bluish green Kornerupine gems come from Madagascar and cats eye cabochons are available from Sri Lanka. Star Kornerupine has been found in Mogok, Myanmar (Burma) but is very rare. Kornerupine was originally found in Greenland as non-gemmy, radiating crystals but later found there as dark green gemmy crystals.
Kornerupine was named in 1884 by Danish mineralogist Johannes Theodor Lorenzen (1855-1884) in honour of Danish geologist, Andreas Nikolaus Kornerup (1857-1883). Kornerup died at age 26 from a lung disease he contracted while on an expedition in Greenland. Although Kornerup died at such a young age, he managed to establish himself as a well-respected geologist in Greenland research. Coincidentally, Johannes Lorenzen also died at a young age, 29, while on an expedition in Greenland in 1884.
