Nigerian pink-green makes yellow round#983

 

Nigerian mixed color round Greenish yellow and pink make a basically yellow, standard round brilliant, interesting, but not too attractive. gemstone The clean round weighs 2.12 carats.

The piece of rough that became this standard round brilliant came from the giant find of tourmaline in Nigeria over 20 years ago.  The overall appearance of the round is that of a yellow, but it is easy to see the greenish part of the stone that has mixed with and pretty much eliminated the pink part of the stone, to make the yellow.  The mixing did not produce a particularly attractive stone this time and I do not highly value it.  The clean stone weighs 2.12 carats which is a pretty average size for the collection.

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.
