An exceptional bright blue green emerald cut turns out to be cuprian.#388

Inclueded cuprian, neon bright blue green emerald cut.  #388 This neon bright, blue green emerald cut came from Mozambique. It has some faint wispy feathers and below average crystal. Still it is so bright from copper that it is eye candy. It weighs 2.44 carats.

It is amazing to me, that after climbing the pinnacles and wandering threw the valleys, of Namibian blue green tourmaline, there is a gemstone that transcends all of them in the same tray.  The gemstone does not have the most saturated color, though it is great and its crystal is not exception since it is prone to faint wispy feathers,  but its neon brightness demands the eyes attention.


Now I didn’t set up the tray, my son did, after the last gem and mineral show the Carnegie museum in Pittsburgh Pa ever held.  So I am not to blame for upstaging the really beautiful blues and greens from Namibia which surround,  this gemstone, that I did not even buy as cuprian.  Which brings up an interesting point.  All of the cuprian tourmaline that I have seen from Mozambique is water worn and it is difficult to see the “neon” look in the material until you cut the gemstone.  Now you might ask, how do I know that this bright blue green gem is cuprian, well that is where my handy dandy spectrometer comes in.  It clearly shows that this 2.44 carat, neon blue green emerald cut is cuprian.  I probably purchased the rough for this beauty, years before copper was discovered by the GIA, in a reverse Alexandrite color changing, cuprian tourmaline, from Mozambique, that I submitted.  I now call the new color changing variety of Elbaite tourmaline “Laurellite” after my first born child.  Its reverse Alexandrite color change is unique in gemstones.



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.
