Semi Precious Stone Alexandrite
These rare gemstones
are named after the Russian tsar Alexander II (1818-1881), the
very first crystals that having been discovered in April
1834 in the emerald mines near the Tokovaya River in
the Urals. This discovery was made on the day of future tsar came to age.
Although alexandrite is the relatively young
gemstone, it certainly had a noble history. Since it shows both
red and green color, the principal colors of old Imperial Russia, it inevitably
became a national stone of tsarist Russia.
