Unique faceted watermelon pink center, green rind, emerald cut. #69

A unique example of cutting a watermelon tourmaline, emerald cut.  #69 This pastel emerald cut consists of a band of green than a wide band of pink and than another band of green. It was cut from a watermelon tourmaline. It has radial flaws in the green bands, but a clean center. It weighs 3.75 carats.

Everyone seems to love watermelon tourmaline,(a crystal with a pink core that runs down the long axis of Elbaite tourmaline that is coated with a green rind.), but it is rare that this distribution of color is useful to the faceter.  I have cut emerald cuts with their crowns of the core color and the pavilions of the rind color or visa verse, but the posted gem is the only one I was able to center the core down the long axis of the gem and have balanced bands of rind on both sides.  The stone is dichroic and this shows up in the darker pink dominated ends of the long ratio emerald cuts.  The core of the stone is eye clean, but the rind, like it is many times, has residual radial flaws.

The posted stone, on its own and not just a unique example of cutting a watermelon tourmaline, is attractive.  If it is looked at under the bright indirect lighting of a fading day, it soaks in color like all pastels do and become quite a sight.  It weighs 3.75 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.
