Achroic, colorless round from Afghanistan#1167

Colorless tourmaline, achroic, from Afghanistan, round This small standard round brilliant is bright and colorless. It probably started out as a light blue piece of rough, but I can not see any color in the finished gem. It is eye clean and weighs .39 carats.

This standard round brilliant is colorless and without inclusions.  It came from Afghanistan and really does produce  some of the purest tourmaline in the world.  The biggest draw back to colorless tourmaline, as a gemstone, is its lack of dispersion, rather than lack of brilliance, when properly polished.  This gem weighs .39 carats and may have started out as a pale blue in the rough.


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.
