A great, clean, yellow green piece of eye candy, copper bearing round. #62

Exceptional yellow green copper bearing round.  #62 This standard round brilliant is a GEM,(exceptional gemstone) with a "neon" look that may come from its copper content. It is eye clean and has great crystal. It weighs 3.17 carats.

This is a beautiful gemstone.  Its acid yellow green color seems to burn a hold threw the little plastic box I store it in.  Its medium toned splendor is augmented by having copper as a chromophore in its chemistry.  I did not buy the rough for this gemstone as cuprian, so I was surprise to find copper’s signature absorption peaks in the gemstone with my spectrometer.  I personally think that copper is helping this yellow green GEM (exceptional gemstone) have that “neon” look that is associated with cuprian tourmaline.  I really have no way of knowing.  This gemstone weighs 3.17 carats and has a color that should get more respect in the Trade.


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.
