Open Ends and Strong shift from Blue to Green, Emerald Cut

Open ended blue emerald cut with shift to blue green in yellow light. This open ended emerald cut has a very nice blue color in natural light, but it shifts strongly to blue green in yellow light. It appears to be eye clean and has good crystal. It weighs.94 carats.

This smaller emerald cut has normal angles on the end, because its ends are open.  Open ends lead to flashy ends and having the corners cut off less.  Taken together this makes an emerald cut with closed ends look significantly different than an emerald cut with open ends, when you look at then closely.  This gemstone also has a stronger shift from pure blue in daylight to a blued green in my yellow light than most tourmalines.  It appears to eye clean and with good crystal.  It weighs .94 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.
