Dichroic pink with growth tubes emerald cut.#527

Dichroic pink tourmaline with growth tubes. This strongly dichroic tourmaline has bright flashy medium toned ends and a hand full of bright parallel growth tubes that flash out from a pale pink a/b background. It weighs 3.44 carats.

Imperfections in a gemstone do not always make it less beautiful or interesting.  Cats eye in tourmaline that are produce by dense formations of growth tubes is a prime example of that beauty and interest in tourmaline.

The posted highly dichroic emerald cut is far from being a candidate to be cut into an cats eye.  Its bright flashing medium tone value ends frame only a handful of perfectly formed absolutely parallel growth tubes.  The dichroic a/b color, a rather pale pink with probably just a touch of brown, is the back drop for the flash of the growth tubes.  Now if the growth tubes had been incorporated into the emerald cut at an odd angle, it would have not added much to the beauty or interest of the gemstone, but these growth tubes are exactly aligned with the edges of the finished gem.  (All of this brought to you by a natural crystal that made it easy.)

At first you might miss the bright thin shafts of flash, but if you look closer they will peak you’re interest and enhance the eye clean, emerald cut, with the excellent crystal that makes the flash so bright.  And even if an inquisitor doesn’t care for the effect, in an otherwise flawless gemstone, at least you had something interesting to say about your beauty.  It weighs 3.44 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.
