A very bright eye clean achroic (colorless) round Afghanistan#702

Bright white with maybe a touch of blue, round I can't see it now, but the rough show a touch of blue. This colorless standard round brilliant is eye clean and bright and weighs 1.22 carats.

Afghanistan produces some of the most outstanding tourmaline in the world.  It is amazing to me how the pastel colors it produces can be so pure and bright.  This small standard round brilliant has a purity of being,without color, to an exception degree.  No hint of gray here, but the rough did have a detectable bit of blue, that I can not pick up, in the finished stone.  Perhaps with younger, better eyes (eyes yellow with time). you can still notice it.  Either way this round gives you a great look at what a well cut and polished “diamond cut” round can blaze in tourmaline.  The only real gemological phenomenon that is lacking in tourmaline is dispersion, when you compare pure tourmaline with some other colorless gemstones (I guess I have to say diamond). It weighs 1.22 carats.

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.
