Medium rich green with slight inclusions, cuprian droplet of color.#175

A medium toned, slightly included green, cuprian droplets of color.  #175 This medium toned green droplet of color has copper, but I can not see it in its visible nature. It is a nice bright stone, that is not bothered by its slight inclusions. It weighs 1.29 carats.

Of all the colors I explored with my spectrometer for copper, the most discoveries of copper were made in greens.  I also had quite few indications of copper in pink/red, but there are technical issues with that color of tourmaline and I am working to verify my results.

This standard round brilliant is an attractive medium toned green, that is not noticeably dichroic, but I still don’t see any visible indications of copper in it.  So it will have to stand before the droplets of color based on its own visible merits.  It easily gain entrance, but I think her cuprian nature was known and factor in.  I really can not keep secrets from the droplets of color, they populate my dreams.  She weighs 1.29 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.
