Fine yellow round seaks help with drift toward green.#997

 

Clear yellow with a touch of green, round This standard round brilliant is eye clean and would like to be a yellow, but has a touch of green. I think that it could be called canary. The gemstone weighs 2.92 carats.

This bright standard brilliant is an example of a yellow with a hope for stardom, falling pray to the evils of green. Now where yellow becomes yellow green in tourmaline varies between peoples eyes.  Even normal eyes have different ratios of color receptors (cones) and the yellow green line is really sensitive to that.  Also eyes go a bit yellow with age.  I have read that the “new” deposit of so called canary tourmaline from East Africa can have a touch of green and still demand the high prices, so I think I will let this stone be a bird for once.and let anyone looking at it decide for themselves where it should fly. The culet of this clean 2.92 carat stone appears to be a tad greener than the crown, but it is really hard for these old eyes to tell.

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.
