Copper plus manganese equals a well saturated purple, round#641

A fine included purple (from copper/manganese), round. Mozambique  #641 This standard round brilliant has the usual inclusion in purple tourmaline from Mozambique. Still the stone is bright and flashy. This rare color indicates copper as a chromophore. It weighs 1.88 carats.

No one should get too blase about well saturated purples in tourmaline.  It is rare and always will be rare because the saturation, if not the actual color, is dependent on both copper and manganese chromophores.  Manganese is pretty common in tourmaline, but copper is not.

This standard round brilliant is included, as most of the purples are, but is still bright and flashy.  It has a medium tone and a very good saturation level unlike most of the iron manganese purples, I have been able to get.   The non-copper purples are darken with either gray or brown.  This round weighs 1.88 carats and is a choice item even if it is moderately included.


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.
