A fine medium light pink oval#273

Nice middle of the road pink oval This pink oval really has no problems to report. Its moderate pink, flashes and loves attention. It has a uniform pink color and weighs 2.95 carats.

I you have been reading many post about the gemstones I have cut, you have probably come to the conclusion that pink/reds are predominately in ovals and rounds, while greens are predominantly in emerald cuts.  This is true and it does not have to do with the shape of the rough completely.  Strong enough dichroism to cause the c axis to be too dense to use as a table is much more a problem with greens than pink/reds.  This does not mean that the c axis does not give problems for some pink/reds.  If the tone level of the gemstone is on the higher side and I cut the table close to being perpendicular to the c axis,  the table tends to undercut when I polish it.  Undercutting appears as an uneven surface that looks like little rivulets.  I have worked many hours trying to reduce or eliminate this condition with moderate success.  In the end, I find that modest undercutting does not really effect the quality of the produced gemstone, still the table is the pathway to the soul of the gemstone and it should be as perfect as you can make it.  Many times the polishing of the table takes the most effort I put into a gemstones, by far.

The posted oval’s moderate tone level represents the boundary between darker tone levels and potential undercutting problems and pink pastels that are some of the easiest tourmaline to polish.   This is just a rough rule of thumb, because tourmaline is too complex to ever yield to a broad generality.  This fine pink oval has all the good gemological properties and weighs 2.95 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.
