Bright and light without a hint of darkness, emerald cut.

Bright open ended emerald cut with only one green hue. This really nice, medium toned, dancing emerald cut has just one green color. No dark closed ends for this gem. It is lightly included and weighs 1.34 carats.

This emerald cut is an example of why it is difficult to make broad generalized statements about tourmaline.  Many tourmalines do not show strong or even noticeably pleochroic/dichroic effects.  There are many tourmalines in my collection that can not be oriented to the c axis (principle axis) by any change in tone level or color.

The posted emerald cut has only one color, but it does appear to be somewhat richer down the c axis.  This increased tone level in the c axis is expected, but can be difficult to verify in longer ratio emerald cuts.  I look at the stone threw the corners to try and get a feeling for how open or different the dichroic colors are before and after I finish an emerald cut.  The lack of darkness in the ends of the emerald cut makes it dances with a nice crisp medium green.  It is lightly included and not being eye clean is shared with many lighter toned greens.  This bright, fun, stone weighs in at 1.34 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.
