How Green is My Tourmaline, VERY, emerald cut

Great classic green tourmaline, emerald cut This gemstone is dichroic, but the darker c axis color is isolated in the ends of the stone. The central window is a great tourmaline green. It eye clean with great crystal. It weighs 6.52 carats.

This green emerald cut is made from a dichroic crystal, but the emerald cut keeps the darker yellower green c axis color pretty well isolated in the ends.  The central window of the gemstone focuses on the really nice a/b axis green with is framed by the darker mixing of the dichroic colors in the end of the gemstone.  You really don’t notice the c axis yellow green color unless you tilt the gemstone to see  it.  This beautiful classic emerald cut tourmaline is brilliantly eye clean and with great crystal.  The extra effort in polishing and using angles that are correct for tourmaline, rather than ones set to try and retain weight, makes this 6.52 carat gemstone a winner.


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.
