A Purple without Copper Oval#1067

Purple oval without copper This oval is a bright, moderately toned purple. It has a bit of scatter toward the girdle that is not distracting. It weighs 3.78 carats.


This gemstone has a place in the collection not because of its great beauty, but it is attractive, or size, though it is a decent size, or clarity, though it is has good crystal or …  It is here because this collection is the result of a quest to cut and collect as many colors of tourmaline as I could assemble.  Now I certainly violated a single minded drive  to never get anything tourmaline that didn’t help fill the color wheel.  I just had to indulge in Namibian blues, Nigerian reds etc. but when something different in tourmaline came along I had to try and get some.  This gemstone is a purple without copper as a chromophore.  It is a mild pastel with a better saturation than some other examples I have purchased, but it just doesn’t have the edge that copper purples have.  Traditionally pinks that had a purplish cast were not highly valued and I think that this gemstone probably falls into that category.

After having written a bit of a put down for this gemstone, I confess that I am actively searching for purples without copper because they are different.  This gemstone at 3.78 carats doesn’t have a relative in the droplets, a bit of information generally not talked about, so the quest goes on.  It is nice, once in while, to value something that doesn’t have a great cost associated with it.




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.
