Lavender Tourmaline, Lavender Tourmaline, Shield Cut, Cuprian#196

A beautiful pure lavender shield cut  #196 This shield cut gemstone is from Mozambique and is copper bearing. It has a medium toned, well saturated lavender color in an eye clean and sparking gemstone. It weighs a beautiful 4.40 carats.

It is probably unnecessary and maybe even childish to type the same color before tourmaline twice in the title of this post.  It is just a way to express how important this color is in my world of color in tourmaline.  Besides being beautiful, well saturated lavender was one of the colors that came out of Mozambique saying something wonderful and different in tourmaline was being found.  What it did not say for years was that something was copper bearing or could produce gemstones in the same league as Paraiba tourmaline from Brazil.  That would have to wait until I sent in a gemstone with the unique property of reverse Alexandrite color change from lavender in natural light to blue green in incandescent light to the GIA for testing. (I call the new variety of tourmaline Laurellite and I have more complete posts about it)

This is a beautiful gemstone regardless of its history or its cuprian nature.  It is a very bright, eye clean and out going shield cut.  Although its medium toned, well saturated lavender color is a strong indicator of its cuprian nature,  I have confirmed its cuprian nature with my spectrometer.  I have pastel purples, mainly from Madagascar that don’t have copper and lack the level of saturation found in the lavenders of Mozambique.  It weighs a treasured 4.40 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.
