Favorite green in the collection is a fighter, round.

Now to be the favorite green in this collection is saying something and it did not come easily.  I purchased the rough for this gemstone well before copper was discovered in tourmaline from Mozambique, in “Laurellites” I supplied the GIA. (Laurellite is a name I have given a new variety of Elbaite that contains copper and demonstrates a reverse Alexandrite color change from purple in natural light to blue in incandescent light.)  The rough has a web of inclusion and could never produce a clean stone.  Still it has a bright wonderful green that is not at all dichroic.  Somehow I know that this included stone was different.  Later when copper was discovered from Mozambique, I just knew that this green round had to be cuprian.  I had an opportunity to test it on a spectrometer, but the spectral width of the instrument did not exceed the visible and could not tell me what I wanted to know. (The stone did produce a wonderfully symmetrical set of two absorption peaks in the visible).  Finally, when I got my spectrometer, that goes farther into the near infrared, I could confirm the presence of copper.  The brightness of this included gemstone could be explained and I knew she was the one. We just had the right chemistry.  There will always be controversy surrounding my decision because she is impure, but we have taken our vows and no amount of money or a new flirtation will change them.  She weighs a comely 6.03 carats and wears a standard round brilliant gown.

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.
