by aac2013 » Dec 26, 2018 I finally purchased a ruby just in time to have my own bit of Christmas red for the holiday. I have looked for a ruby for quite some time. This one is 4.02 carats and GRS graded as vivid red pigeons blood (though she really is a chameleon). Sometimes she displays bright red and other times a bit of purple comes through. She is from a newer mine in Mozambique and is very clean clarity wise. As I had to compromise somewhere, she is heated (GRS [H]) but no other treatments.
