Substanial bronze to olive green shield cut.  #198 This shield cut has a medium dark, bronze to olive green color. It is eye clean and has fine crystal. It weighs 6.31 carats.

Sometimes you never know which part of the collection will spark the appreciation for tourmaline that I hope to instill in my fellow man.  When I spent a day with a curator of gems and minerals at a large eastern college, she was most excited by the posted gemstone.  Now it is a large medium dark bronze to olive green shield cut that is not highly valued by the trade.  The color is also one of the more common colors of tourmaline, but the gemstone was hiding something deeper than its color revealed.  It had been the terminus of a large crystal, that went threw chemical changes that oscillated and crystallized tourmaline into alternating bands of darker green and almost colorless bands.  This made for a good time under her microscope.  I bought it and cut it to bring a more realistic and broader based color balance to the collection.  This solid member of the collection weighs 6.31 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.
