Another Achroite Challange in the Round#1078

 

Shifty Achroite Round This 4.41 carat, very pale pastel has been declared colorless which in tourmaline goes by Achroite. It is eye clean and very bright, but is pretty shifty for such a pale gemstone.

I have never tried to describe so many different colors in tourmaline at one time before.  My inconsistencies on the official boxes that protect them and keep them ordered is a bit disconcerting.  Didn’t I try to spend that extra time with the newly completed additions to the collection that they deserved?  Have I failed as a cutter?  Will I be sued for violation of the covenant?   Enough soul searching, because this bright, eye clean round holds at least part of the truth.  It has clear on the box, a tired way of saying achroite, and even such a pale stone shifted color and tone level on me, as I looked at it under a yellowish light verse daylight. Now I will stay with clear because natural light is the determiner, but its other persona is a tea richer than some, just reviewed, that are obviously not an achroite.  I think I just said it again, in a different way.  To really appreciate many tourmaline you have to live with the gemstone.  Take it for a walk or to the grocery store etc., but don’t buy it in a jewelry story and expect it to look just like it did there, when you get home.   Oh and by the way, setting gemstones can be a color adventure also.  This standard round brilliant weighs 4.11 carats and I have its number now.

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.
