When I received this semi- preformed piece of rough in the mail, with other bi-colors from Afghanistan, I thought it was too go to be true. It also had a decent price. Now this rarely happens and it makes you wonder what is your missing, Read further and you may see the explanation (I believe) for the mystery.
This bi-color is a great example of a gemstone from Afghanistan. It is pure except for a slight veil caused by laser testing the gemstone for its chromophores. It is exceptional because there is not transitional area between the two colors that is universal with green to pink zoning, along with being a beautiful gemstone. I have seen other examples of this color distribution from Afghanistan, but none as nice. I have never seen the same thing from any other location. The rough had been worked on by a cutter who had some bad luck with bi-colors, not an uncommon occurrence and he decided to sell, rather than cut, the piece. It did not give me any problems in cutting or polishing and it is a novelty addition to the collection, rather than having new colors to add.
