This emerald cut was oriented parallel to the c axis. This presents alternating slices of pie, of the richer c pink and paler a/b pink color, The round is eye clean and bright. It weighs 7.51 carats.
I would have cut this standard round brilliant with its table perpendicular to the principal (c) axis if it was reasonable. It wasn’t, so I cut the emerald cut with the table parallel to the c axis. With that orientation you get alternating slices of pie with both dichroic colors appearing face up in the round. In this case the c axis color is a nice bright pink and of course dominates, but doesn’t eliminate the paler a/b. When people look close enough at the gem, they find it surprising to see the four slices of a beautiful pie. This is a good sized pie at 7.51 carats. It is eye clean and of excellent crystal.

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.
