Rolling round with yellow, a droplet of color.#911

Nicely saturated yellow round This 1.84 carat yellow round is clean and without a greenish or brownish cast. This makes it a rare and valuable gem.

 

The brilliant round standard cut is weighs 1.84 carats and will make a wonderful droplet of color.  They like yellow in tourmaline almost as much as I do.   It appears to be eye clean.   At first I check the stone under a yellowish light, which is produced by one of those modern twisty fluorescence lights in a yellow shade and makes the gemstone a very uniform medium rich toned yellow.  So as I started to write, I decide that I ought to expend a little more effort and confirm the general properties of the gemstone in gray natural light (bluer).  Well I started to chuckle, which I don’t do often, because the gemstone has become much more dichroic with a richer more golden yellow blending into a paler purer yellow.  Wait now before conclusions are reached, the sun just momentarily peaked out and I caught a few rays.  The yellow was back to being a very nice. uniform, well saturated yellow.  The gem is really pretty well behaved, but I have warned you before that you should see your precious tourmaline under different lighting conditions to truly appreciate it or not.

I put this in a separate space because the most important point in looking at this gemstone under different lights is to confirm that it does not have a greenish cast under any reasonable conditions.  It is also does not have a significant amount of brown because of a low level of saturation (purity of color).  All this makes the tourmaline rare and difficult to get a hold off.   I think that the principle competitors are the Japanese who are willing to spend large amounts of money on selected gemstone like Paraiba  tourmaline and jade.

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.
