A different look darker “chrome” tourmaline#230

Darker "chrome" Dravite the Species Tourmaline This oval has the typical darker pure green look of "chrome" Dravite tourmaline. It appears eye clean, but the dark tone hides flaws. It weighs 1.21 carats.

This gemstone is made of a different member of the tourmaline group than most of the gemstones in this collection.  It is a vanadium/chrome (most of the time the vanadium dominates) colored Dravite, the species.  Dravite has magnesium in it and no lithium, that is in  Elbaite, the principle gemstone making tourmaline.  The green that is produced has a different visual impact and is both quit desirably and expensive.  It is general too dense/dark to be cut effectively in larger stones.  This oval 1.21 carats show its color mostly threw its flash.  Which is dark by may standards, but it is a great color.


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.
