What can I say, I like even gray, in the color world of this round.#1105

Beautiful, unstable gray round with plenty of presences. Round This beautiful gray is unfortunately unstable and now has a faint flaw one half of the way across the stone. It is still quite a display stone since it has plenty of presences. It weighs 4.73 carats.

I was once looking threw a list of gemstones and their colors presented by the Gem Institute of America GIA.  I always like to see which colors are not included in the list of colors for tourmaline.  The most notable, this time, was gray.  Now I know that gray will never be among the top ten hit for color in any gemstone, but I think it can be beautiful.

This standard round brilliant has a great pure gray that is the best in the collection.  I am sure that it is not just a heated something else that got cooked too long.  It does seem to float around between a bit of a bluish cast to a bit of a brownish cast depending on the light.  Now that we have savored the glory of this stone, I need to tell its dark side.

I started out cutting a shield cut from this really bright, glassy, eye clean piece of crystal.  The points began to break and then a razor thin flaw began to propagate into the heart of my gray.  I took the strongest action I could and ground the triangular semi-finished shape into a round.  The crack continued and is now about one half of the way across the crystal.  It is not reflective and looks like a thin, dark, rather wavy line.  Still my gray is unstable, but worth finishing as a great example of a tourmaline color that is appreciated only by a select group of color addicts like me.  It weighs a much reduced 4.73 carts.

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.
