An amazing GEM green emerald cut.

Non-dichroic, highly saturated, eye clean green tourmaline. In Elbaite, the most common species of gem tourmaline, this emerald cut is a GEM. That is the highest grade of gem in both cutting and gemological properties. It weighs 4.45 carats.

To be a GEM (highest quality gemstone) in the world of green tourmaline is saying a lot.  The competition from chrome tourmaline and cuprian tourmaline is intense.  Now I am not saying that this gem can match the level of saturation (purity of color) of the best chrome tourmaline or the neon qualities of the best cuprian tourmaline, but in its world of Elbaite (most common species of tourmaline in gemstones) this emerald cut is a GEM.  I don’t  think that it can get better than this bright, richly toned, highly saturated, non-dichroic green GEM.   The GEM appears eye clean and with a fine, complete set of seven row of facets that meet the standards of the collection.  I want to reiterate that the GEM is NOT dichroic.  This is not really rare in lighter toned gems, but in an Elbaite that is this rich in tone, it is most unusual.  It also points out the fact that you CAN NOT us dichroism as a means to determine if a gemstone is a tourmaline or not.  Finally if you really want a treat, take this GEM and put it in my secret place next to a twisty florescent light inside a yellowish shade and the green blaze will amaze.  This GEM weighs 4.45 precious 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.
