|Stunning natural, un-polished specimen of Brazilian Alexandrite. The specimen is @ 47 x 22 x 20mm overall with a large
piece of Alexandrite protruding from a mica matrix. The exposed protrusion is @ 18mm wide, 5mm thick and 16mm
exposed length. There appears to be additional smaller Alexandrites within the matrix or the large protrusion may
continue through the matrix. It is not possible to tell how far this goes into the matrix or what is really hidden without
removing the matrix material.
|Alexandrite is an extremely rare and was originally found in Russia. The mineral was named for the former
Czar of Russia, Alexander II, and was first discovered in the Ural Mountains of Russia on Alexander's day of
birth. The Russian Alexandrite has become almost impossible to find. Thanks to our friends in Brazil,
another limited supply of Alexandrite has been located.
The most sensational feature about this stone is its amazing ability to change its color. Green or
bluish-green in daylight, alexandrite turns a soft shade of red, purplish-red or raspberry red in incandescent
light. A unique chromium balance in Alexandrite gives it this curious color changing characteristic. These are
natural specimens of Alexandrite, not a synthetic corundum.
In 1987 alexandrites were discovered in a place called Hematita in Minas Gerais, Brazil. The Brazilian
alexandrites showed both a distinctive color change and good clarity and color. The color of the Brazilian
stones is admittedly not as strong a green as that of Russian alexandrite, but the color change is clearly
Alexandrite is a stone for serious enthusiasts and collectors, a truly understated stone. Its uniqueness and
high value are not evident at first sight. The mysterious color change will only occur on exposure to different
light sources at the correct intensity. If you really get involved with alexandrite, you will be absolutely
fascinated by this gem.
