ROUGH INDUSTRIAL ALEXANDRITE BRASIL ORIGIN.

THE COLOR OF ALEXANDRITE CHANGES UNDER DIFFERENT LIGHTING CONDITIONS. IF VIEWED IN DAYLIGHT, ITS COLOR IS GREENISH BLUE TO DARK YELLOW-GREEN. IF VIEWED IN INCANDESCENT OR CANDLE LIGHT, ITS COLOR IS PINK TO RED. ALEXANDRITE IS A VERY RARE AND HIGHLY VALUABLE GEMSTONE, AND UNTIL RECENTLY WAS EXTREMELY DIFFICULT TO OBTAIN DUE TO ITS RARITY. HOWEVER, NEW SOURCES IN BRAZIL AND TANZANIA HAVE MADE THIS GEMSTONE AVAILABLE AND MORE MAINSTREAM ON THE GEMSTONE MARKET.  
PEOPLE ALWAYS TALK ABOUT THE QUALITY OF RUSSIAN ALEXANDRITES, BUT AS THERE HAS BEEN NO PRODUCTION FOR 100 YEARS, THE POINT IS LARGELY IRRELEVANT. EXPERTS IN LATE 19TH CENTURY ANTIQUE JEWELRY ACKNOWLEDGE STRONG COLOR RESEMBLANCES BETWEEN BRAZILIAN AND RUSSIAN ALEXANDRITES, BUT THE RUSSIAN STONES ARE SAID TO BE SLIGHTLY DARKER AND LESS CLEAN THAN THEIR BRAZILIAN COUSINS. 
FROM A HISTORICAL PERSPECTIVE AND BECAUSE OF ITS LORE AND ITS IRREVOCABLE ASSOCIATION WITH LAST OF THE RUSSIAN TSARS, IT IS CLEAR THAT RUSSIAN ALEXANDRITES ARE THE MOST VALUABLE IF THEIR ORIGIN CAN INDEED BE PROVEN. IN TERMS OF QUALITY HOWEVER, IT IS UNCLEAR HOW THE RUSSIAN STONES WOULD COMPARE WITH SUBSEQUENT DISCOVERIES OF FINE ALEXANDRITES FROM SRI LANKA, AFRICA, INDIA, AND BRAZIL.
TOP ALEXANDRITES ARE EXTREMELY RARE, BUT EVERY DEPOSIT SEEMS TO PRODUCE SOME OUTSTANDING STONES FROM TIME TO TIME. UNFORTUNATELY, THERE HAS BEEN LITTLE PRODUCTION OF ALEXANDRITES FROM ANY DEPOSIT IN RECENT YEARS. OCCASIONAL ALEXANDRITES ARE STILL FOUND IN INDIA AND SRI LANKA, AND SOME STONES ARE STILL DISCOVERED IN THE ALLUVIAL GRAVELS OF AFRICA, AND MADAGASCAR, BUT FEW STONES ARE EVER AVAILABLE. THE BRAZILIAN MINES ARE THE ONLY COMMERCIALLY OPERATIONAL DEPOSITS, BUT PRODUCTION THERE IS LIMITED AND LARGE STONES ARE RARE.
