THIS IS INDEED A VERY MYSTERIOUS RUBY. IT WAS OBTAINED AS POSSIBLY FROM BURMA AND UNHEATED/UNTREATED, BUT THIS COULD NOT BE 100% CONFIRMED. THERE ARE, HOWEVER, NO CLEAR INDICATIONS THAT IT COULD NOT BE AN UNHEATED BURMESE RUBY, BUT THIS MAY ONLY BE CONFIRMED BY LABORATORY TESTING. SHOULD A LAB TEST CONFIRM THAT IT IS INDEED BURMESE, THE REAL VALUE COULD BE UP TO US$800 (R7200.00) AND MORE THAN TWICE THIS AMOUNT IF UNHEATED.
