An extremely faint trace of green in the IceT emerald cut.#516

An extremely light green emerald cut for IceT time, with growth tubes. This extremely pale green emerald cut has a plan of growth tubes parallel to is keel. This distorts the stones reflections and makes it interesting. It weighs 1.82 carats.

This emerald cut goes back awhile, to a time when I thought that the straight sharp fagot of tubes in the pavilion of this emerald cut were rutile crystals not growth tubes.  (Now I have never heard of rutile in tourmaline, but I have since seen a lot of growth tubes.)  I can not say that I really planed this cut the way it turned out, but it is interesting.  The exceptional light green body (IceT material) of this gemstone is very transparent and flawless if you don’t count the tubes.  The growth tubes are all in the same plane (parallel to the c axis) and the plane is about 45 degrees to the table.  They are also perfectly parallel to the keel of the emerald cut.  Now looking down, I don’t perceive a flaw, but some weird disturbance in the force governing the world of reflectance in tourmaline.  I thought it was cool the day I saw if for the first time and I still do.  Maybe it is still the kid in me.  This optically perverse gem weighs 1.82 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.
