Strongly dichroic forest green round.#139

Highly dichroic, darker forest green round. #139 This standard round brilliant appears to be eye clean. It is easy to see This gemstones dichroic nature is easy to see because it is so dark face up and not to the side. It appears to eye clean. It has reasonable flash for a darker stone and weighs 1.99 carats.

Most of the smaller rounds and many of the larger ones are cut with their table perpendicular to the c axis (principle axis).  This is to get the best level of tone and an even color, face up, in the stone.  It also obscures how dichroic they are.  Well with this forest green, the depth of color is so much higher, face up, (c axis) than the a/b axis which is seen from the side of this standard round brilliant that it was worthy of mention.  The round appears to be eye clean and has reasonable flash for such a dark gemstone.  It weighs 1.99 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.
