Question
I have an emerald that was purchased in northern  India- approx 1.14ct. When I wnet to set in at my jeweller to get it set as a ring, he said that this was a specail emerald worth  called a Constantine emerald. I tried to search this type of emerald on the internet but could not find any info. Could you please let me know if this exsists, and what its worth is/could be?

Hi Isabelle,

I know of many references to emerald connected with the emperor Constantine but I am not farmiliar with a specific type of emerald called a 'Constantine'. Did your jeweller say why it was a Constantine Emerald? What makes it this type of emerald? I'm sorry I am not farmiliar with this term. Good Luck.
