Dichroic yellow green and yellow brown droplet of color.

Dichroic, yellow green and brown green droplet of color This darker standard round brilliant best side is flashes of brownish green over a yellow green. It has dynamic color because it is dichroic. It appears to be eye clean and weighs 1.27 carats. For unity a droplet of color.

There has been quite a bit of looking at this standard round brilliant stone before its color was figured out.  At first glance it seemed almost like a gray, but then brownish flashes appeared.  Now that doesn’t make a lot of sense,  so the investigation continued.  It was not being cooperative and refused to confirm any color.  Under the yellowish light it turned a darker shade of yellow green without the brownish flash.  But this was not enough to end the inquisition.  Another round of natural light and the brownish flash appeared over a darker yellow green ground.  Then the stone was flipped and the truth revealed.  This darker mysterious stone was dichroic and clearly had a brown green and yellow green side.  Would this less that stellar example of tourmaline color be accepted by the droplets.   Now that it had come clean and it is eye clean, acceptance was assured since the quest is for all colors not just the eye candy show offs.  This trying stone has a medium dark tone level and weighs 1.27 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.
