baby blue and baby pink bi-color from Afghanistan#946

Great Blue/Pink bi-color from Afghanistan The pastel blue/pink bi-color weighs 6.41 carats and is pure except for a slight veil at the junction of the colors. It is a very nice gemstone.

 

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.

About Bruce Fry

I was born in Summit, NJ in 1947 and graduated from Summit High School in 1966. I graduated from the Colorado School of Mines in 1970 and after spending another year in graduate school, I left to see the world of Brazil. After spending some more time discovering myself, I ended up working for the Commonwealth of Pennsylvania for 32 years as an Air Quality Engineer in the Department of Environmental Protection. I retired in 2007 and took up faceting gemstones again after a long hiatus that reached back to my twenties. I had started cutting cabochons when I was 13 and bought my first faceting machine when I was 15, but ran out of money and time until I retired.
My great love in gemology is tourmaline and the collection presented here represents my effort to get as much beauty and variety in the colors of tourmaline as I can. I was particularly lucky in being able to get unheated cuprian tourmaline before copper was discovered in gem grade tourmaline from Mozambique.
