Maybe a touch of blue in an Achroite, round#798

Very faintly blue, Achorite from Afghanistan, round I have posted about quite a few of these Achorites. Most are standard rounds brilliants that may have a touch of blue. I have seen the blue under direct sunlight. This gemstone weighs .44 carats. Afghanistan

I just rediscovered the key to finding the blue in these nearly colorless standard round brilliants from Afghanistan, direct sunlight, how new and novel.  This gemstone still almost failed the blue test.  It is very bright and flashy and weighs .44 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.
