True blue that so sweet in the round.#1029

Namibian Blue in the Circle of Winners. This smaller standard round brilliant is a great blue. It is eye clean and weighs 1.54 carats. It comes from Namibia.

I think that Namibia should be declared a world treasure for the blue tourmaline (indicolite) it produces.  It also produces other colors that I don’t want to put down, but blue is the name of the game for me.  My principle problem with Namibian blue is that is it very expensive for what you get and almost impossible to get in larger sizes.  Also there is a lot of heating going on, even before the tourmaline is cut, so some stones develop flaws that run.  (I am speculating that heating cause the problem, but I have not run into the running with other tourmaline) This problem is pure torture.  You’re trying to grind out a flaw, but as the facet gets bigger, the tourmaline propagates the flaw deeper into the stone.   Aggressive grinding and quick stock removal is the only hope one has of saving the beautiful blue.  You would not think that a smaller blue like this one would be fragile, but I have problems with developing flaws that don’t take long to flaw the diminutive stone.

This smaller standard round brilliant is a blue treasure.  Its tone level, saturation and hue are right on the beauty mark.  It could be a droplet, but others stand in line for that honor and this gemstone is perfect enough to stand on its own.  This bright eye clean treasure weighs in at 1.54 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.
