Bright cool refreshing mint blue green, cuprian round#184

Medium toned minty blue green round.  #184 This standard round brilliant is very bright and a nice medium toned minty blue green pastel. But I don't see the neon look of copper in the gemstone. It is eye clean and weighs 3.10 carats.

Another unexpected copper discovery with my spectrometer that is in a much more desirable (expensive) color, minty blue/green.  The eye clean stone has a very bright, medium light pastel color, but really does not have the neon look to me.  Because of it copper content and color, it could be called a paraiba type gemstone by the trade since there is no mention of neon look in the definition.  Still I have hear of reports that some cuprian from Paraiba in Brazil do not really have the neon look and I have certainly seen it in my tourmalines.  Without the neon look, I don’t think that gemstones should have an increased value for their copper content.   Be that as it may,  I like this minty want to be and it catches my eye at 3.10 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.
