Good Size green oval with light growth tubes.#249

A very nice larger green oval This green oval has nice even color, and is eye clean except for a few deeply buried growth tubes. It is very transparent for its size, which is 8.32 carats.

A nice, spicy, larger oval tourmaline with a good uniform, medium toned green. Wow I got a lot into that sentence.  The only thing I can see that lessen the glory with this gemstone is a few deeply buried ghostly growth tubes.  Growth tubes come about because of problems with the crystal growing in the c axis direction.  If the are numerous enough and not too coarse, you can make cat eyes out of the included tourmaline.  These growth tubes are hardly noticeable and do not come threw the table.  So let the green shine on in a really transparent tourmaline that has very good size.  It weighs 8.32 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.
