A Blue that walks to a different drummer, Round

no images were found

Most blue tourmaline really like yellowish/incandescent light.  It really fires up the stone even if the blues can tend to become greens.  Well here is a standard round brilliant that just has to be different.  I read on the box that this is a pale blue stone and when I look at it in the morning light, just as the sun is clearly illuminating my room, it is a glorious medium blue without any green.  That means the tone level is right on for this gemstone and I am beginning to wonder why I ever thought it was pale.  Then I put it under my yellowish light source and the blue washes out and some green appears.  It is just not the same stone.  It still appears to be eye clean and weighs 1.84 carats.

I have written and I will write this many times.  You MUST look at any piece of tourmaline under different light sources to know what color you have.  Even under relatively “normal” lighting, tourmaline can be very dynamic with color.  And I don’t think that the lighting in a jewelry store is necessarily normal in your world.  The one I worked with for a while has such blue lights that I always wonder what a new stone would look like there.  They also sold a lot more aquamarine and sapphire that ruby.

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.
